ChemInform Abstract: Cyanoacetylene and Its Derivatives. Part 9. Electrophilic Heterocyclization of β‐Aminocyanoethylenic Acetals.

Abstract

The primary amines (II) add to the cyanoacetylenic acetals (I) to afford the expected title compounds (III) as E/Z‐mixtures.

Chemistry of heterocyclic compounds at the A. E. Favorsky Irkutsk Institute of Chemistry, Siberian Branch of the Russian Academy of Sciences, over 50 years (Review)

“…By varying the ratio of the reagents and the reaction conditions it is possible to bring about the one-pot assembly of polyconjugated heterocyclic systems 77 having unusual electrophysical characteristics [242][243][244][245][246][247]. …”
