89% With potassium carbonate In N,N-dimethyl-formamide at 20℃; for 18 h; General procedure: To a solution of N-hydroxysalicylamide (0.5 g, 3.26 mmol) in anhydrous DMF (5 ml) was added 2a or 2b (3.26 mmol) and freshly calcinated K2CO3 (1.35 g, 9.78 mmol) and the mixture was kept, with stirring at the room temperature overnight. DMF was removed in vacuo and the residue was treated with water (10 ml) and then extracted with CH2Cl2 (5 ml). The organic layer was separated, washed with water, dried over anhydrous CaCl2, and purified by flesh chromatography on silica gel using CH2Cl2 as eluent. Dichloromethane was evaporated in vacuo. The resulting residue was benzo[d]oxazol-2(3H)-one 11. The water layer was acidify by hydrochloric acid, filtered and washed with water. The resulting residue was compound 12a(b).

Stage #1: With 1,1'-carbonyldiimidazole In tetrahydrofuran at 60℃; for 2.5 h; Heating / reflux
Stage #2: With hydrogenchloride In water at 10 - 15℃; for 0.5 h;
A solution of intermediate 1 (1,92 M in THF) was stirred at 60°C. A solution of CDI (3,84 M in THF) was added over 30 min. under reflux to the aforementioned solution and refluxed for another 2 hours at 60°C. The reaction mixture was cooled to 40°C and the solvent evaporated. After completion, the remaining residue was quenched with water and acidified with 12N HCI to pH 2. The mixture was stirred for 30 min. at 10- 15°C and the resulting precipitate filtrated, washed with ice-water and dried under reduced pressure at 90 °C. Quantitative Yielding 3-Hydroxybenzisoxazole (intermediate 2).

Triphenylphosphine (164 mg, 0.625 mmol, 1.25 equiv) was then added. After 2 min, DIAD (123 lL, 0.625 mmol, 1.25 equiv) was added dropwise. TLC (Hex/EtOAc, 1:3) after 30 min revealed the reaction was complete. The THF was removed in vacuo. The residue was partitioned between 0.1 M NaOH (50 mL)and CH2Cl2 (100 mL). The organic layer was separated, then the aqueous layerwas washed a further three times with CH2Cl2 (100 mL). The aqueous layer was acidified with 1 M HCl (10 mL), then extracted into CH2Cl2 (2 100 mL),washed with brine (50 mL), dried (Na2SO4), filtered and concentrated to yield the 3-hydroxybenzisoxazole 2a: mp = 143 146 C; δH (400 MHz, d6-DMSO)7.09–7.17 (m, 3H, Ar), 7.29 (d, J = 7.6 Hz, 1H, Ar), 11.63 (s, 1H, OH); δC(100 MHz, CDCl3) 156.2, 143.8, 129.4, 124.2, 122.7, 110.2, 110.1.

Benzo[d]isoxazol-3-ol (35AKU-44) (71)
To a solution of salicylhydroxamic acid (1.53 g, 10 mmol) in THF (40 ml) was added a solution of carbonyldiimidazole (1.62 g, 20 mmol) in tetrahydrofuran (20 ml).
The mixture was stirred at reflux for 4 hrs. before evaporation to dryness.
Water (20 ml) and conc. HCl (aq.) (5 ml) were added and the solution was refrigerated (5° C.) for 30 min.
The resulting precipitate was collected by filtration and washed with 2M HCl.
The solid material was dissolved in methanol and concentrated in vacuo yielding 725 mg (54percent) of the title compound 71. TLC (10percent methanol in DCM): Rf=0.2. HPLC-MS (Method A): M+=136.1 (UV/MS(percent)=94/100).1H-NMR (400 MHz, CDCl3, MeOD): δ=7.73 (1H, m); 7.56 (1H, m); 7.38 (1H, m); 7.28 (1H, m); 3.87 (1H, s).

The final solvent ratio (H2O:EtOH:THF)was (3:1:1). The mixture was stirred at room temperature for 30 min under visiblelight irradiation using a halogen lamp (HALOPAR 20 75 W 230 V 30-GU10;Osram, Italy). The reaction was monitored by TLC. After completion of thereaction, EtOAc (30 mL) was added. The aqueous layer was collected andconcentrated under reduced pressure at 25 C to obtain pure sample containing Agnanoparticles that was characterized by UV–Vis and TEM analyses. The organicphase was collected, dried over anhydrous MgSO4 and filtered. The solvent wasevaporated under vacuum using a rotatory evaporator and then the residue was purified by a short plug of silica gel using (Hexane:EtOAc, 1:1) to obtainhydroxamic acids 2a–j in 81–92percent yield.
