PROCEDURE

实验过程

A sample of (1R,2S,4S,5R)-2-benzyloxycarbonylamino-4-iodo-7-oxo-6-aza-bicyclo[3.2.1]octane-6-carboxylic acid tert-butyl ester (43.3 g) was dissolved in benzene (580 mL) prior to the addition of Bu3SnH (27.8 g) and AIBN (0.7 g). The resulting mixture was warmed to a gentle reflux for 3 h. After cooling, the solvent was removed and hexane was added. The resulting white solid was collected by vacuum filtration to give (1R,2S,5R)-2-benzyloxycarbonylamino-7-oxo-6-aza-bicyclo[3.2.1]octane-6-carboxylic acid tert-butyl ester (29.5 g). MS found: (M+Na)+=397.4.
