Abstract

α, β-Epoxy ketones, prepared using the polyleucine catalysed asymmetric epoxidation of enones, can be converted into α-substituted β-hydroxy ketones via carbonyl alkylation with Grignard reagents followed by ytterbium triflate catalysed semi-pinacol rearrangement of the resulting epoxyalcohols.
