Flavothebaone. Part VIII. Hofmann degradation of flavothebaone trimethyl ether ψ-methine methiodide
Abstract
The Hofmann degradation of flavothebaone trimethyl ether ψ-methine has been re-examined and shown to give, as major product, 2-[3,6-dimethoxy-2-(2-oxopropyl)phenyl]-7,8-dimethoxy-1-vinylnaphthalene (6). A minor product, previously considered to be the ketone (9), has been identified as the cyclic enol ether (11) derived from (6).
