PROCEDURE

实验过程

A solution of (3S,4S)-3-[(1R)-1-benzyloxycarbonyloxyethyl]-4-[(1R)-1-benzyloxycarbonylethyl]-1-(t-butyloxycarbonylmethyl)azetidin-2-one (81.50 g) in ethanol (800 ml) was subjected to hydrogenation at room temperature in the presence of 10% palladium-carbon (8.15 g) under atmospheric pressure, followed by filtration to remove the catalyst. The filtrate and the washings were combined and evaporated to give (3S,4S)-3-[(1R)-1-hydroxyethyl]-4-[(1R)-1-carboxyethyl]-1-(t-butyloxycarbonylmethyl)azetidin-2-one.
