실험 절차

To a solution of p-nitrobenzyl α-[4-cyclopropylmethoxycarbonylthio-3-phenoxyacetamido-2-oxoazetidin-1-yl]-α-(1-hydroxyethylidene)acetate (904 mg) in a mixture (9.5 ml) of tetrahydrofuran and hexamethylphosphorotriamide (20:1) are added methanesulfonyl chloride (0.26 ml) and triethylamine (0.37 ml). After 2 hours, the reaction mixture is poured into ice water, and extracted with chloroform. The extract solution is washed with water, dried, and evaporated to give p-nitrobenzyl α-[4-cyclopropylmethoxycarbonylthio-3-phenoxyacetamido-2-oxoazetidin-1-yl]-α-(1-methanesulfonyloxyethylidene)acetate (1.12 g). Yellow foam. IR: νmaxCHCl3 3426, 1785, 1722-1704br, 1640, 1601, 1160, 1175, 986 cm-1. NMR: δCDCl3 0.32-1.25m5H, 2.57s3H, 2.72s3H, 3.99d(7 Hz)2H, 4.55s2H, 5.33-5.99m4H, 6.82-7.62m7H, 8.21d(8.5 Hz)2H.
