The Oxidation of Some Steroidal Dienes and Trienes with Chromic Acid
Abstract
The chromic acid oxidation of steroidal 2,4- and 3,5-dienes and 2,4,6-trienes is shown to take place at the secondary termini of the alkenes rather than at the allylic positions and is rationalized in terms of a sequence of 1:4-additions of chromic acid.
