New synthetic methodology utilising 1,2-dioxines and stabilised phosphorus ylides: a highly diastereoselective cyclopropanation reaction
Abstract
A new method is described for the synthesis of diastereomerically pure cyclopropanes from substituted 1,2-dioxines 1a–c and stabilised phosphorus ylides 2a–e.
