Abstract
The coupling of Fischer carbene complexes with 3-alkynyl-2-heteruaromatic c arboxaldehyde derivatives has been examined. The reaction affords pyrones f used to furans or thiophenes in a single step. The compounds are stable eno ugh for isolation. If the carbene complex features a remote alkene substitu ent, a subsequent Diels-Alder reaction can occur. (C) 2001 Elsevier Science Ltd.
