Abstract
The reactions of 3,3-dialkyl-3,4-dihydroisoquinoline cyclic azomethines with the methyl ester and p‑toluidide of iodoacetic acid gave stable quaternary ammonium salts which were suitable dipoles for [3+2] cycloaddition reactions. Azomethines activated by iodomethylation react with potassium cyanide and malonodinitrile. How to Cite Surikova, O. V.; Mikhailovskii, A. G.; Vakhrin, M. I. Chem. Heterocycl. Compd. 2009 , 45 , 1473.
