(Chemical Equation Presented) Stereodiad sulfones 18a and 18b are key intermediates for polyketide synthesis. This note describes the synthesis of 18a and 18b from enantiopure epoxide 2. The two sequences have been optimized for large-scale synthesis to g

Enantiopure cycloheptadienyl sulfones 6 and 7 are diastereoselectively epoxidized to yield epoxyvinyl sulfones 8, 9, 14, and 16 in high yields and diastereomeric ratios. Syn and anti methylation of epoxides 8, 9, 14, and 16 enables access to all eight pos
