Abstract

There are prepared dienones of the Narwedin type of the formula in which the substituents are described in Claim 1. These compounds are obtained from the corresponding esters of the formula I by electrochemical oxidation. The said compounds can be used as starting materials for the preparation of Amaryllidaceae alkaloids.
