Metal-dependant stereoselectivity in the Pauson-Khand cyclization of N-propargyl-γ-amino vinyl sulfones

Abstract

An efficient enantioselective route to N-propargyl-γ-amino vinyl sulfones has been developed, and their Pauson-Khand cyclization has been investigated. The stereoselectivity of the reaction depends both on the structure of the substrate and on the nature of the metal-carbonyl promoter. ©ARKAT.
