A novel intramolecular rearrangement of isothiazolethioacetamides into 1, 3-dithietanecarboxamides is described, together with the synthesis of a new cephamycin derivative (YM-09330) having a 1, 3-dithietane structure at the 7β-position. This compound showed strong antibacterial activity, especially against gram-negative organisms.
报道了一种新型异噻唑硫乙酰胺分子内的重排反应,生成1,3-二硫杂环戊烷羧酰胺,并合成了一个新的头孢菌素衍生物(YM-09330),该衍生物在7β-位具有1,3-二硫杂环戊烷结构。该化合物显示出强大的抗菌活性,特别是针对革兰氏阴性菌。
