A new type of 5, 6-cis-carbapenems (racemic) having a sulfonyl group in the C-6 side-chain were synthesized by employing the synthetic methodology reported in our previous papers, and an alternative stereocontrolled synthesis of these 5, 6-cis-carbapenems was achieved starting from 8-oxo-7-azabicyclo [4.2.0] oct-3-ene (14) via an intramolecular aldol condensation as the key step. Chiral 5, 6-cis-carbapenems were also synthesized from (1S, 6R) -8-oxo-7-azabicyclo [4.2.0] oct-3-ene (29), which was derived from cis-1, 2, 5, 6-tetrahydrophthalic anhydride. The carbapenems thus obtained proved to be highly stable to the mouse kidney homogenate, and most of them showed good antibacterial activity as well as potent β-lactamase inhibitory activity.
利用我们之前论文中报道的合成方法,合成了一种新型5,6-顺式-碳青霉烯类化合物(外消旋体),其C-6侧链上含有磺酰基团。通过以分子内aldol缩合作为关键步骤,从8-氧代-7-氮杂双环[4.2.0]辛-3-烯(14)开始,实现了这些5,6-顺式-碳青霉烯类化合物的替代立体控制合成。从顺-1,2,5,6-四氢邻苯二甲酸酐衍生得到的(1S,6R)-8-氧代-7-氮杂双环[4.2.0]辛-3-烯(29),也合成了手性5,6-顺式-碳青霉烯类化合物。所得到的碳青霉烯类化合物在鼠肾匀浆中表现出高稳定性,其中大多数化合物不仅具有良好的抗菌活性,还显示出强效的β-内酰胺酶抑制活性。
