Monocyclic β-lactams related to nocardicins were enantioselectively synthesized from phthal-imidoacetyl chloride and hexahydro-1, 3, 5-triazines (4) via a [2+2] cycloaddition reaction. The preparation and biological activity of some typical acyl derivatives are also described.
与诺卡菌素相关的单环β-内酰胺是通过[2+2]环加成反应,从邻苯二甲酰亚胺氯化物和六氢-1, 3, 5-三嗪(4)选择性合成的。还描述了某些典型酰基衍生物的制备及生物活性。
