Highly diastereoselective addition reactions of a radical derived from a β-ethoxycarbonyl sulphoxide

Abstract

The 1-ethoxycarbonyl-1-p-tolylsulphinylethyl radical 2, generated by iodine abstraction from 1, adds to the alkenic bond in allyltriphenylstannane or in hex-1-ene with very high diastereoselectivity (>98%).
