Asymmetric Aminohydroxylation of Heteroaromatic Acrylates

Abstract

N-, S- and O-heteroaromatic acrylates were aminohydroxylated with generally high regio- and enantioselectivity. While pyridylacrylates are not amenable towards this process, the corresponding N-oxides proved to be a useful substitute, allowing the access to biologically important pyridine substituted taxolTM side chain analogs.
