Preparation of thieno[2,3-b]pyrroles starting from ketene-N,S-acetals
摘要:
Thieno[2,3-b]pyrroles 4 can easily be synthesised in two different ways by using phenyl isothiocyanate and activated methylene compounds. The priority of the formation of the thiophene or pyrrole ring is investigated. (C) 2003 Elsevier Science Ltd. All rights reserved.
