A convenient synthesis of the paclitaxel side-chain via a diastereoselective Staudinger reaction
摘要:
The N-benzylidene derivative of (S)-(-)-1-(p-methoxyphenyl)propyl-1-amine, obtained by a new resolution procedure, exhibits moderate selectivity in the reaction with 2-acetoxyketene; the (S)-(-)-1-(p-methoxyphenyl)propyl group can be oxidatively cleaved from the resultant beta-lactam, an important precursor for taxane semi-synthesis.
