摘要

Abstract The reaction of cuprous acetylides with aryl halides bearing a nucleophilic ortho substituent provides a versatile route to heterocyclic substances. The present work portrays the ease with which polyheterosystems can be constructed with this reaction. The synthesis of 2-substituted 7-iodofuro [3, 2-c] pyridines, 2-substituted furo [3, 2-b] pyridines, and 3- substituted lH-thieno-[3, 4-b]-2-pyran-l-ones (thiaisocoumarins) is described. The latter ...
