Procedure

To a stirred solution of 2,2,2-trichloroethyl α-[4-cyclopropylmethoxycarbonylthio-3-phenoxyacetamido-2-oxoazetidine-1-yl]-α-(2-bromo-1-hydroxyethylidene)acetate (330 mg) in methylene chloride (6 ml) is added aluminum chloride (330 mg) at room temperature, and the mixture is stirred for 60 minutes. The reaction mixture is poured into ice cold diluted hydrochloric acid, and is extracted with ethyl acetate. The extract solution is washed with diluted hydrochloric acid and water, dried, and evaporated to give 2,2,2-trichloroethyl 7-phenoxyacetamido-3-oxocepham-4-carboxylate (300 mg). Foam. IR: vmaxCHCl3 3420, 1780, 1685 cm-1. NMR: δCDCl3 3.37s2H, 4.53s2H, 4.85s2H, 5.07d(4)1H, 5.20-5.73m2H, 6.8-7.7m6H.
