Synthesis of 5,5′-bis-benzofurans and 5-arylbenzofurans
摘要:
A facile synthetic route of the tandem Claisen rearrangement/aerobic Wacker-type oxidative cyclization toward 5,5'-bis-benzofurans 2 and 5-arylbenzofurans 3 starting with bis-allyl aryl ethers 4 or allyl aryl ethers 5 with good yields is described. Skeletons 4 or 5 was prepared from 4,4'-biphenol (1) in moderate total yields via the known protocol. (C) 2013 Elsevier Ltd. All rights reserved.
