- Abstract
The article offers information on the course for the reaction of 1-di(ethoxycarbonyl)methyl-1-methyl-4-phenyl-1,2,3,6-tetrahydropyridinium bromide with dimethyl acetylenedicarb-oxylate in the presence of triethylamine. The reaction was conducted under analogous conditions but in place of the expected azonine derivative, column chromatography of the reaction mixture gave a 25 per cent yield of the substituted pyrrolidine 3, the 2-ethenyl group of which contains three alkoxycarbonyl substituents.
