实验过程

126 μl of diisopropylethylamine and 132 μl of diphenylphophoryl chloride were simultaneously added, whilst ice-cooling, to a solution of 218 mg of 4-nitrobenzyl (5R, 6S)-6-[(1R)-1-hydroxyethyl]-2-oxo-1-carbapenam-3-carboxylate dissolved in 3 ml of dry acetonitrile, and the mixture was stirred at the same temperature for 1 hour. At the end of this time, a solution of 243 mg of the crude (2S, 4S)-2-(N,N-dimethylcarbamoyl)-1,1-dimethyl-4-mercaptopyrrolidinium salt [prepared as described in Example 4-(1)] in 2 ml of dry acetonitrile and 144 μl of diisopropylethylamine were added to the mixture, whilst ice-cooling. The mixture was then allowed to stand at the same temperature for 5 hours and then for 2 days in a refrigerator. At the end of this time, the reaction mixture was worked up in a similar manner to that described in Example 6. The crude product was dissolved in a mixture of 15 ml of tetrahydrofuran and 15 ml of a 0.1M phosphate buffer (pH 7.0) and hydrogenated at room temperature for 2 hours in the presence of 200 mg of 10% w/w palladium-on-charcoal. At the end of this time, the reaction mixture was worked up and purified in a similar manner to that described in Example 6, to afford 56 mg of the title compound.
