Abstract

Reactions of 2-(pyridin-3-yl)- and 2-(pyridin-4-yl)pyrroles with propargyl chloride yielded the expected N-allenyl derivatives. At the same time, propargylation of isomeric 2-(pyridin-2-yl)pyrrole afforded an unexpected N-propargyl derivative. The surprising outcome of the reaction was analyzed.
