74% With bromine; triphenylphosphine In dichloromethane for 4h; Inert atmosphere; 3 (3) Synthesis of Compound S3: (3aS,4S,6afl)-4-(5-Bromo-pentyl)-tetrahvdro- thieno[3,4-c/limidazol-2-one Triphenylphosphine (0.390 g, 1 .50 mmol) was dissolved in anhydrous DCM (1 -2 mL) under nitrogen and transferred with a syringe to a solution of bromine (77 μΙ, 1 .50 mmol) in anhydrous DCM (3 mL) at 0°C. This solution was stirred for 10 min. The resulting yellow slurry was transferred with a syringe to a suspension of alcohol S2 (0.230 g, 1 .00 mmol) in anhydrous DCM (2 ml_). After complete dissolution of all reactants the reaction was monitored by TLC. After 4 h a white precipitate formed and the reaction was quenched by the addition of Na2S203solution (10 ml_, 0.1 M, aq) resulting in a colour change from yellow to colourless. Water (10 mL) was added and the organic layer was separated from the aqueous layer. The aqueous layer was extracted with DCM (3χ20 mL), and the combined organics were washed with water (3 x 10 mL), dried with Na2S04and the solvent removed in vacuo. The crude product was purified using column chromatography (DCM:MeOH, 90:10) to yield the bromide S3 as a colourless solid (0.220 g, 74%).

The solution was cooled to -78°C and DIBAL (6.23 mL, 7.12 mmol, 1 .0 M in DCM) was added dropwise. After stirring at -78 °C for 20 min the solution was allowed to warm to room temperature and was stirred for 2 h. The mixture was again cooled to -78°C and the reaction was quenched by the addition of MeOH (4.5 mL), followed by MeOH:H20 (15 mL, 2:1 ). The solvent was removed in vacuo and the residue was purified by column chromatography (DCM:MeOH, 90:10) to give alcohol S2 as a colourless solid (0.570 g, quantitative).

YieldReaction ConditionsOperation in experiment
94% With sodium tetrahydroborate; In N,N-dimethyl-formamide; at 0℃; for 0.25h; D-Biotin (1.00 g, 4.09 mmol) was dissolved in 20 mL DMF at 70 C and allowed to cool to rt. TEA (0.83g, 1.14 mL, 8.19 mmol) was added, followed by pentafluorophenyl trifluoroacetate (1.60 g, 0.98 mL, 5.73 mmol). The reaction was allowed to stir for 1 h at 0 C and became pink. Solvent was reduced to 1 mL in vacuo and the crude material was triturated with cold diethyl ether. The pFp ester product was recovered as a white solid (1.54 g, 96%). Biotin-pFp ester (1.00 g, 2.44 mmol) was dissolved in 10 mL DMF and cooled to 0 C. A flask containing a suspension of NaBH4 (3.4 mmol) in dry DMF (5 mL) was also cooled to 0 C. The pFp-ester was transferred dropwise via a cannula over 15 min and the mixture was stirred at 0 C. The reaction was followed by TLC and upon completion the cold mixture was acidified with 1 N HC1 and reduced to 1 mL in vacuo. The residue was triturated with cold diethyl ether and the product alcohol was recovered as a white solid (0.528 g, 94%). The alcohol (0.528 g, 2.29 mmol) and TEA (0.39 ml, 1.2 eq) were dissolved in DMF (10 mL) and added dropwise to a stirred solution of 4-nitrophenyl chloroformate (4-NCF, 1.38 g, 6.87 mmol, 3.0 eq) in DMF (10 mL) over a period of 1 h at -10C. The reaction mixture was allowed to warm to rt, stirred overnight, and subsequently and reduced to 1 mL in vacuo. The residue was triturated with cold diethyl ether. The nitrophenol carbonate product was recovered as a white solid (0.96 g, 95%). Fmoc-L-Lys-OH (1.03 g, 2.83 mmol, 1.3 eq.) was suspended under argon in anhydrous DMF (10 ml) containing DiPEA (0.50 ml, 1.3 eq.). To this white suspension, a clear solution of the nitrophenol-carbonate (2.18 mmol, 1.0 eq.) in anhydrous DMF (10 mL) was added drop wise under argon at rt over a period of 2 h. The reaction mixture was stirred for additional 4 h at rt, before the solution as acidified to pH 2 with 1 N HC1. All volatiles were evaporated under reduced pressure and the residue was triturated with cold diethyl ether. The crude product was purified by column chromatography (DCM : MeOH 95 : 5 v/v) to give the Fmoc-protected ncAA as a white solid. The Fmoc- protected ncAA was dissolved in 20% piperidine in DMF (5 ml) and stirred for 1 h at r.t.. All volatiles were removed under reduced pressure and the residue was triturated with cold diethyl ether. Drying of the residue in vaccuum yield the pure ncAA as a white powder (0.622 g, 71 %). 1H-NMR (D6-DMSO, 400 MHz): delta = 1.30-1.45 (m, 6H), 1.50-1.65 (m, 4H), 1.85 (m, 2H), 2.65 (d, J = 12.2 Hz, 1H), 2.84 (dd, J= 5.0 Hz, J= 12.2 Hz, 1H), 2.95 (m, 2H), 3.13 (m, 1H), 3.42 (m, 1H), 3.66 (m, 1H), 3.85 (dd, J= 13.8 Hz, J = 1.0 Hz 1H), 3.93 (t, J= 7.5 Hz, 2H), 4.17 (dd, J= 8.2 Hz, J= 7.3 Hz, 1H), 4.35 (dd, J= 8.1 Hz, J= 7.2 Hz, 1H), 7.11 (t, J= 5.4 Hz, 1H), 8.50 (br, 3H), 8.53 (br, 1H), 8.68 (br, 1H).13C-NMR (D6-DMSO, 100 MHz): 13C-NMR (CDCI3, 100 MHz): delta = 171.44, 163.29, 156.82, 64.00, 61.61, 60.35, 59.79, 55.95, 52.28, 39.10, 30.05, 29.35, 29.02, 28.78, 28,73, 25.91, 22.05.
