Regioselective ring-closing metathesis on terpenoid acrylates and acrylamides
摘要:
A series of acrylate esters was prepared by treatment of representative terpenoid aldehydes with allyl or vinyl magnesium bromide followed by reaction with acryloyl chloride. In all cases, ring-closing metathesis (RCM) resulted in regioselective formation of unsaturated lactones through metathesis of the acrylate and terminal olefins. After condensation of farnesal with a primary amine, a parallel series of reactions led to Formation of the corresponding lactam. (C) 2001 Elsevier Science Ltd. All rights reserved.
