The Tetracyanoethylene Catalysed Methanolysis of Androstane 2,3-Epoxides
Abstract
Unlike other acidic systems, the tetracyanoethylene catalysed methanolysis of androstane 2,3-epoxides proceeds normally without giving products arising from the transannular participation of a 5α,6α-epoxide, a 5α-hydroxy group or a 5(6)-ene.
