Reaction Steps

DEAD (676 mg, 3.88 mmol) was added via syringe with stirring and under argon, to a solution of ester 27 (590 mg, 2.59 mmol), alcohol 26b (707 mg, 2.64 mmol), and TPP (1.018 g, 3.88 mmol) in 8 ml dry THF. The reaction mixture was stirred overnight under argon at 25° C. and then treated with 30% hydrogen peroxide. Ether was added (approximately 20 ml) and the organic layer was separated, washed with brine, and dried over MgSO4. The crude product was adsorbed onto silica gel and purified via flash chromatography with elutions of 95/5 and 90/10 (v/v) (Hex/EtOAc), respectively. Evaporation of solvent yielded 505 mg (41%) of a white solid.
