Direct, Stereoselective Synthesis of the Protected Paclitaxel (Taxol) Side Chain and High-yield Transformation to Paclitaxel

A short, efficient approach to the p-methoxybenzylidene-protected paclitaxel (Taxol) side chain through benzaldehyde benzoylimine-chiral enolate condensation, followed by DDQ-mediated oxazolidine formation and hydrolysis is described; the C-7-triethylsily

Highly stereocontrolled and efficient preparation of the protected, esterification-ready docetaxel (Taxotere) side chain

A high-yield synthesis of the p-methoxybenzylidene-protected docetaxel (Taxotere) side chain, a useful derivative for efficient, epimerization-free esterification of the 7,10-bis[(trichloroethoxy)carbonyl] derivative of 10-desacetylbaccatin III for the preparation of docetaxel, has been effected; the C-4 and C-5 stereocenters of the 1,3-oxazolidine are generated with complete (≥99%) stereocontrol whereas that at C-2 is produced with 96% selectivity.
