Brønsted-acid-catalyzed coupling of electron-rich arenes with substituted allylic and secondary benzylic alcohols
摘要:
p-Toluenesulfonic acid and triflic acid catalyze efficiently the coupling of electron-rich arenes with allylic and benzylic alcohols. Reactions are conducted under mild conditions, in air, and in the absence of solvent. (C) 2007 Elsevier Ltd. All rights reserved.

photooxidation of latifolin() and dihydrolatifolin () gave novel xanthan derivatives() and () involving a crucial step of photooxidative demethylation followed by cyclisation. Similar reaction of the closely related propane gave, interestingly the benzofuran .The propene . lacking free hydroxyl or double bond, gave only the quinone indicating that quinones are intermediates in the above oxidations. The allyl alcohol
