摘要

p-Nitrobenzyl (6R, 7S)-3-hydroxy-8-oxo-7-phenoxyacetamido-1-azabicyclo [4.2. 0] octa-2- ene-2-carboxyate (6) was synthesized utilizing rhodium (II)-or acid-catalyzed cyclization of iodonium ylide (5). The iodonium ylide (5) was easily prepared from the corresponding β- keto ester (4) and [(diacetoxy) iodo] benzene in good yield.
