Abstract

Abstract: y-Alkoxy-a $-unsaturated sulfones are readily available in both racemic and scalemic form, the latter either by asymmetric induction from achiral building blocks or from readily available scalemic starting materials. These electron deficient olefins serve as excellent substrates for [3+ 21 cycloadditions involving the intermediacy of trimethylenemethane-palladium complexes. The highly diastereoselective ...
