A simple and rapid entry to 5-alkyl (aryl)-5-hydroxy-3,4-diarylfuranones and 3a-hydroxy-1-aryl-2,3a,4,5-tetrahydronaphthofuranones via a tandem esterification and oxidative cyclization process
摘要:
A synthesis of 5-hydroxy-3,4-diarylfuranones and related derivatives is accomplished by the reaction of arylacetic acid with alpha-bromoketone in the presence of base and atmospheric oxygen. A variety of compounds were synthesized in good to excellent yield and many are of potential biological interest. (C) 2002 Elsevier Science Ltd. All rights reserved.
