Diastereoselective intramolecular Diels-Alder reactions towards the synthesis of a taxol C-ring precursor

Intramolecular Diels-Alder reactions have been used for the synthesis of cis-hydroisobenzofuranones 23 or 21, which represents a potential precursor of taxol C-ring. Easy preparation of β-ketoesters 7a and 7b is also described.
