Crystalline 1beta-methyl-2-formyl carbapenem pNB esters were prepared by osmium-mediated oxidative cleavage of the corresponding 2-vinyl derivatives. Reduction of the 2-formyl compounds gave the corresponding 2-hydroxymethyl derivatives, which are key intermediates for the anti-MRS carbapenem candidate (1).
通过介导的相应的2-乙烯基衍生物的氧化裂解,制备结晶的1β-甲基-2-甲酰基碳青霉烯pNB酯。2-甲酰基化合物的还原得到相应的2-羟甲基衍生物,它们是抗MRS碳青霉烯候选化合物(1)的关键中间体。
