A rapid access to coumarin derivatives (using Vilsmeier–Haack and Suzuki cross-coupling reactions)
摘要:
A four-step preparation of compounds containing a coumarinic moiety is presented. This synthesis involves notably a Suzuki cross-coupling reaction (performed in aqueous Media) and a ring closure by formation of delta-lactone. (C) 2002 Elsevier Science Ltd. All rights reserved.
