A FACILE ROUTE TO FUSED HETEROCYCLES WITH AN EXOCYCLIC METHYLENE BY INTRAMOLECULAR NUCLEOPHILIC AMINATIONS TO ACETYLENE

Sasaki, Tadashi,Shimizu, Ikuo

, p. 1225 - 1230 (2007/10/02)

The novel method for synthesis of fused heterocycles with an exocyclic methylene was investigated.The terminally acetylene-substituted heterocycles 3a-c and 6a-d were converted to the fused heterocycles with an exocyclic methylene 4a-c and 7a-d by intramolecular nucleophilic amination to acetylene part.
