Abstract

Substituted thiophenes have emerged as a class of important heterocycles because of their presence in a broad spectrum of natural and synthetic molecules with diverse biological properties,(1-4) material characteristics,(5) and utility in organic synthesis as versatile intermediates.(6, 7) The general synthetic approaches to such thia-heterocycles involve either the functionalization in the α- and β-position of the preconstructed thiophene skeleton(8, ...
