Studies in sulfur heterocycles. Part 12.1 Use of 5,6-dihydrobenzo[b]thiophen-7(4H)-one in the synthesis of condensed sulfur heterocycles
Abstract
Readily available 5,6-dihydrobenzo[b]thiophen-7(4H)-one has been used as a convenient intermediate for the synthesis of several condensed heterocyclic systems and substituted benzo[b]thiophenes.
