L-Threonine was transformed, stereospecifically, to a versatile β-lactam (5a) in 3 steps. This β-lactam was further converted to a key intermediate (25) for the synthesis of thienamycin and its biologically active analogues. Furthermore, the compound 5a was changed to iodides (18 and 23), cyanides (19 and 24), chloromethylketone (26) and aldehydes (30 and 31) which appear to have a latent potential
3个步骤将L-苏氨酸立体定向转化为通用的β-内酰胺(5a)。将该β-内酰胺进一步转化为合成噻菌霉素及其生物活性类似物的关键中间体(25)。此外,化合物5a变为碘化物(18和23),氰化物(19和24),氯甲基酮(26)和醛(30和31),它们似乎具有潜在的潜力,可以作为碳青霉烯类化合物的合成前体。
