FIELD: organic synthesis.
SUBSTANCE: invention relates to a method for preparing N-dibenzoylpaclitaxel (formula I 
) via esterification of 7-protected baccatin (III) with reactive carboxylic acid derivatives of general formula II 
(wherein R1 is aryl or heteroaryl) and single-step removal of protecting ester groups under acid conditions. Compound I can be suitable for preparation of paclitaxel and its analogues.
EFFECT: simplified synthetic procedure.
