合成路线1
该中间体在本合成路线中的序号：(XV)Oxocarbapenam (XII) was converted into vinyl phosphate (XIII) by treatment with diphenylphosphoryl chloride and diisopropylethylamine. Displacement of the phosphate group of (XIII) by 4-mercaptopyrrolidine-2-thione (IV) yielded carbapenem sulfide (XIV). After hydrogenolytic cleavage of the p-nitrobenzyl ester of (XIV) in the presence of Pd/C and KHCO3, the resulting potassium carboxylate salt (XV) was condensed with isobutyryloxymethyl iodide (XVI) to furnish the title compound.
