Reaction of Conjugated Systems containing Nitrogen. VII. Adduct of N-Cinnamylidenemethylamine with N-Methylmaleimide

Abstract

N-Cinnamylidene- or N-(p-dimethylaminocinnamylidene)-methylamine (III or VII) reacts with N-methylmaleimide (IV) to give a 1 : 2-adduct. The structures (Va and VIII) of the adducts were proposed from nuclear magnetic resonance measurements.
