Sulfur-Alkyne Cyclizations for Formation of Dihydrothiophenes and Annulated Thiophenes

Cycloisomerization of homopropargylic thiols to dihydrothiophenes is promoted by group VI metal carbonyls. Related thiacyclization transformations under basic and radical conditions are also described, including regioselective formation of benzothiophenes from aryl methyl sulfides and alkynes.

Studies Directed Toward the Regioselective Carboxylation of the 4-Oxo-4,5,6,7-Tetrahydrothieno-[3,2-C]pyridine Ring System

Carboxylation of 4-oxo-4,5,6,7-tetrahydro[3,2-c]pyridine was achieved using a metallation/carbonylation strategy with desired regioselectivity provided by the existing oxo directing group.
