Addition reactions of heterocyclic compounds. Part XL. Methyl propiolate with some quinolines, isoquinolines, and phenanthridines
Abstract
Reactions of some quinolines, isoquinolines, and phenanthridines with methyl propiolate have been investigated; the structures of the products, usually benzoindolizines, have been deduced from their u.v., n.m.r., and mass spectra.
