ABSTRACT:
An efficient protocol for the synthesis of taxol, taxol analogs and their intermediates is described. The process incudes the attachment of the taxol A-ring side chain to baccatin III and for the synthesis of taxol and taxol analogs with variable A-ring side chain structures. A rapid and highly efficient esterification of O-protected isoserine and 3-phenylisoserine acids having N-benzyoloxycarbonyl groups to the C-13 hydroxyl of 7-O-protected baccatin III is followed by a deprotection-acylation sequence to make taxol, cephalomanninne and various analogs, including photoaffinity labeling candidates.
