Synthesis of Allylic Sulfones and Their Conversion to Dienoic and Trienoic Acids

Abstract

Abstract The Ramberg-Bäcklund2 method for the construction of carbon-carbon double bonds should in principle allow for the conversion of allylic sulfono-acetates to their corresponding dienoic acids (e. g. 1 → 2). Similarly a 2,4-pentadienyl sulfonoacetate should permit access to a trienoic acid(e.g. 3 → 4).
