2-Monosubstituted-1,3-Oxazolidines as Improved Protective Groups of N-Boc-Phenylisoserine in Docetaxel Preparation

Didier, Eric,Foque, Elie,Taillepied, Isabelle,Commercon, Alain

, p. 2349 - 2352 (2007/10/02)

A new route for semisynthetic docetaxel, 1, is desribed using 2-monosubstituted-4-phenyl-1,3-oxazolidine-5-carboxylic acids in esterification of 7,10-O-diTroc-10-desacetylbaccatin III (4).Subsequent deprotection of esters 10(+10') afforded title compound 1 without removal of the Boc group.
