Control of diastereofacial selectivity in the nucleophilic epoxidation of γ-oxygenated-α,β-unsaturated sulphones
摘要:
Epoxidation of gamma-oxygenated-alpha,beta-unsaturated sulphones 4-8 with lithium t-butyl hydroperoxide proceeds with moderate to high diastereoselectivity to give 2-phenylsulphonyl oxiranes 9-13. The sense of diastereoselectivity is dependent on the steric bulk of the alkyl substituent at the gamma-centre.
