Diastereoselective intramolecular Diels-Alder reactions towards the synthesis of a taxol C-ring precursor
摘要:
Intramolecular Diels-Alder reactions have been used for the synthesis of cishydroisobenzofuranones 23 or 21, which represents a potential precursor of taxol C-ring. Easy preparation of beta-ketoesters 7a and 7b is also described. (C) 1997 Elsevier Science Ltd.
