Participants

Reaction Steps

To a solution of 20B (500 mg, 1.87 mmol) in 10 mL of DCM was added Dess martin periodinane (1.03 g, 3 mmol) at one portion at rt. The mixture was stirred at rt overnight and was quenched by 20 mL of NH4Cl aq (Sat'd) solution. The mixture was extracted by DCM (5 mL×3) and the combined DCM layers were dried over Na2SO4. Solvent was remove under vacuum and the residue was purified by silica gel chromatography (Hexane:EtOAc 2:1(v/v)) to give the title compounds (20C) (510 mg, 90%). LC-MS (ESR): m/z=266 (M+H)+.
