标题:Asymmetric synthesis of taxol side chain
发明人：FARINA VITTORIO; HAUCK SHEILA I
权利人:BRISTOL MYERS SQUIBB CO
摘要:The present invention relates to a process for the preparation of (3R, 4S)-3-hydroxy-4-phenyl-2-azetidinone derivatives which are useful intermediates in the synthesis of taxol from baccatin III, said process comprises reacting an acyloxyacetyl halide with an imine derived from L-threonine; and to compounds of formula (III) which are produced in said process: ##STR1## wherein Ar is phenyl; R 1 is hydrogen, an acyl radical of a carboxylic acid, or a carbonic acid ester radical; R 2 is hydrogen or a carboxy protecting group; and R 3 is hydrogen or a hydroxy protecting group.
