摘要

The reaction of acetylenedicarboxylic esters with a variety of nucleophiles selected by reference to a general scheme (I) affords a number of heterocyclic systems, including pyrroles, furans, thiophenes, quinolines, pyrrolinones, and thiazolinones among the cases investigated. The broad utility of the scheme is indicated as well as some evidence on the course of the reaction. The course of additions to the triple bond is determined by the ...
