摘要
A new catalytic asymmetric two-step or one-pot method for the preparation of the C-13 side-chain of paclitaxel (Taxol) and derivatives of the general formula (I) in the form of an acid, salt or ester, in which R represents an aryl group or alkyl group, R1 represents an aryl group or alkyl group, Y represents O, H or alkyl, and X1 represent -CH2-Ph, alkyl, aryl, SiR3 (where the silyl group is a common protective group) or other suitable protective group.
