摘要
An efficient cascade approach to alpha-hydroxy-beta-amino acid derivatives is reported, which goes through a 1,3-dipolar cycloaddition of carbonyl ylides and N-benzoylbenzyl imines and followed by hydrolysis under acidic conditions. This is the first example of using N-benzoylbenzyl imine as dipolarophile for 1,3-dipolar cycloaddition with carbonyl ylide, which provides a direct and convenient access for the one-pot synthesis of paclitaxel side chain and its derivatives.
