95% With ZrCl4-Mg(ClO4)2 composite In neat (no solvent) at 20℃; for 0.133333h; Typical experimental procedure for the onepotsynthesis of benzyl acetate General procedure: A mixture of 4-methoxy benzyl alcohol (1b, 1 mmol),acetic acid (3 mmol), 2 mol% ZrCl4-Mg(ClO4)2 catalyst was stirred at room temperature for the time specified inTable 5. After completion of reaction (monitored by TLC),the solid or liquid product was filtered and washed with25 ml diethyl ether and water. The organic layer wassuccessively washed with saturated NaHCO3 solution. Theorganic layer was dried over anhydrous sodium sulfateand evaporated of the solvent under reduced pressure toprovide a residue which was passed through a short padof silica gel (60-120 mesh) using hexane as eluent to providethe analytically pure acylated product (please seeAppendix S1).Note that as we know that esterification is a reversiblereaction, to avoid this reversible we used every time activatedmolecular sieves as dehydrating agent/waterabsorbing agent. We have not mentioned it in our actualexperimental procedure.

With N,N′,N′′,N′′′-hexadecyltrimethylammonium bis(trifluoromethylsulfonyl)imide; Novozym 435 (immobilized Candida antarctica lipase B) at 50℃; for 4h; Green chemistry; Enzymatic reaction; Lipase-catalyzed synthesis of flavour esters in sponge-like ionic liquid (SLILs) Three mmol of citronellol, geraniol, nerol or anisyl alcohol, and 1, 2 or 3mmol of acetic acid were added to 3mL screw-capped vials with teflon-lined septa. Then, the corresponding amount of [C16tma][NTf2] was added to reach a final IL concentration of 60 or 70% (w/w) with respect to the mass substrates. Reaction mixtures were pre-incubated at 50°C for 10min, resulting in fully clear monophasic systems. Then, 80mg of MS13× per mmol of carboxylic acid were also added. The reaction was started by adding Novozym 435 (40mg/mmol of carboxylic acid) and the reaction was incubated for 4h at 50°C while shaking (300rpm), or under 4W microwave irradiation (which provided a 50°C constant temperature). For products analysis, aliquots (20μL) were taken at selected times and suspended in 500μL octane, and the resulting biphasic mixture was shaken to extract the products. The resulting mixture was centrifuged at 14,000rpm for 10min. Finally, 300μL of the octane extract were added to 100μL of a 100mM ethyl propionate (internal standard) solution in octane, and the final solution was analyzed by CG. For full recovery of the flavour ester products at 4h, the reaction mixtures were consecutively centrifuged four times at 14,000rpm (15min) and at room temperature, 21, 10 and 4°C, which resulted in a top liquid phase of flavour ester and a bottom solid phase containing the SLIL. For the case of anisyl acetate, the reaction mixture was cooled in an ice bath for 3h, and the resulting solid mixture was placed in a centrifugal filter, then centrifuged at 16,000rpm (10min) and at 0°C. This resulted in a top SLIL solid phase, which was retained inside the filter, and a bottom liquid phase of anisyl acetate. For all cases, a sample (10μL) of the resulting flavour ester phase was dissolved in 1mL acetone-δ6, then analyzed by 300MHz 1H NMR and 282MHz 19F NMR, in a Brucker AC 300E spectrometer for SLIL detection. All experiments were carried out in duplicate.

With water; dihydrogen peroxide Potassium phosphate 50 mM; Potassium chloride 20 mM; 2 Determination of Perhydrolysis (OPD Assay)The perhydrolytic activity assay described below was used to determine the amount of peracid formed in the reaction. In these assays, the solution comprised 50 mM potassium phosphate pH 7.5, 10 mM ester substrate, 29 mM hydrogen peroxide, 20 mM potassium chloride, and 10 mM O-phenylenediamine.When using water insoluble ester as the acyl donor, an ester adsorbed fabric swatch was used as the substrate, prepared as described above (“Preparation of Substrate”).Perhydrolytic activity was measured by monitoring the absorbance increase at 458 nm of oxidized O-phenylenediamine (OPD) by peracid generated with the enzyme. The perhydrolytic activity assay solution was prepared in the same manner as the hydrolytic activity assay solution, except that OPD was added to the assay solution to a final concentration of 10 mM. The OPD solution was prepared immediately before conducting the assay by dissolving 72 mg OPD (Sigma-Aldrich, dihydrochloride) in 19.94 mL of the same buffer and the pH was adjusted by slowly adding 60 μL of 13.5 M potassium hydroxide. The pH was measured and if needed, small quantities of potassium hydroxide were added to return the pH to the original pH of the buffer. Then, 495 μL of this OPD solution were added with the other assay components to a final assay volume of 0.990 mL. An assay quenching solution was also prepared by dissolving 36 mg OPD in 20 mL 100 mM citric acid and 70% ethanol.The assay was typically conducted at 25° C. The assay was started by pipetting 100 μL of assay solution before the addition of the enzyme into 200 μL of quenching solution to determine the amount of perhydrolytic components and background absorbance in the assay solution at time 0. Then, 10 μL of enzyme were added to the assay solution to a desired final concentration which produced approximately 10 nanomoles of peracid per minute. A timer was started and 100 μL aliquots were taken from the assay solution and added to 200 μL of quenching solution at various times, typically 2, 5, 10, 15, 25, 40, and 60 minutes, after adding the enzyme. The quenched assay solutions were incubated for 30 minutes to allow any remaining peracid to oxidize the OPD. Then, 100 μL of each quenched assay solution was transferred to a 96-well microtiter plate (Costar) and the absorbance of the solution was measured at 458 nm by a spectrophotometric plate reader (Molecular Devices, SpectraMAX 250). The amount of peracid in each quenched sample was calculated using a standard curve generated under the above conditions with peracetic acid at varying concentrations in the assay solution (without enzyme).Perhydrolysis/Hydrolysis Ratio:Perhydrolysis/Hydrolysis ratio=Perhydrolysis measured in the Perhydrolysis assay/(Total acid detected in the hydrolysis assay-Perhydrolysis measured in the perhydrolysis assay)The results of these experiments are provided in FIGS. 7, 10 and FIG. 11. FIG. 7 provides a graph which shows the ratio of perbutyric acid to butyric acid generated by various enzymes from 10 mM tributyrin and 29 mM hydrogen peroxide in 40 minutes. FIG. 10 shows the ratio of perbutyric acid to butyric acid generated by various enzymes from 10 mM tributyrin and 29 mM hydrogen peroxide in 4, 10, and 30 minutes. FIG. 11 shows the ratio of peracetic acid to acetic acid generated by various enzymes from 10 mM triacetin and 29 mM hydrogen peroxide in 4 and 10 minutes. The results obtained in these experiments indicated that M. smegmatis perhydrolase homologues exhibited a ratio above 1 in the OPD/GC assays described above, while other classes of enzymes exhibited ratios significantly below 1.Table 2-1 provides data showing the perhydrolysis activity of various homologues described herein on triacetin, as compared to the wild-type M. smegmatis perhydrolase. The results provided in Table 2-2 indicate that the perhydrolase has activity over a broad range of substrates. In addition to the results provided in these Tables, FIGS. 8 and 9 provide data showing that the perhydrolase of the present invention has broad pH and temperature range activiti

S6 S7Citronellol acetate DihydromyrcenolScheme 1 : Screening of terpenoids in olefin cross-metathesis catalyzed by catalyst Cla[0063] The reaction was run in ethylacetate solvent and the results are summarized in Table 1.[0064] Table 1 : Screening of terpenoid compounds S6-S7 in olefin cross-metathesis[0065] Terpenoid compounds having only one double bond were reacted. When citronellol acetate S6 was reacted with n-butyl acrylate (2 eq.) Ol in AcOEt in the presence of 1 mol% of catalyst Cla, the expected product P4 was obtained in 43% isolated yield. [0066] Terpenoid compounds having two double bonds were reacted. The second double bond was masked, for instance as the hydrated form. The reactivity of dihydromyrcenol S7 was evaluated. S7 can be considered as a derivative of citronellene where one double bond is masked as a hydroxyl group. The double bond could be regenerated later from the alcohol through a simple elimination reaction. When S7 was reacted 17h at 60°C with n- butyl acrylate (2 eq.) Ol and in the presence of 1 mol% of catalyst Cla, the expected olefin cross-metathesis product P5 was obtained in an isolated yield of 71%.
