Intermediates in the autoxidation of a non-conjugated cyclic diene

Abstract

The isolation of a 5-hydroperoxide which has been postulated as an initial intermediate in oxidative transformation of carota-1,4-dienes into 1,5-epidioxy derivatives was facilitated by using 14-acetoxycarota-1,4-diene 1c; the present results allowed us to substantiate the aspects for the autoxidation pathway in non-conjugated 1,4-diene systems.
