Synthesis of 2-benzoyl-4-(2-hydroxybenzoyl)phenols by catalytic domino ‘Michael–retro-Michael–Mukaiyama-aldol’ reactions of 1-aryl-1,3-bis(silyloxy)buta-1,3-dienes with 3-formylchromones
摘要:
The domino reaction of 1-aryl-1,3-bis(silyloxy)buta-1,3-dienes with 3-formylbenzopyrylium triflates, in situ generated from 3-formylchromones, afforded a variety of 2-benzoyl-4-(2-hydroxybenzoyl)phenols. (c) 2007 Elsevier Ltd. All rights reserved.
