A facile and one-pot synthesis of a series of novel spiropyrrolidines/pyrrolizidines with β-lactam substituent has been accomplished through 1,3-dipolar cycloaddition reaction of alkenyl esters derived from β-lactam aldehyde as dipolarophile with the dipole azomethine ylide derived from 1,2- and 1,3-diketones and secondary amino acids. The synthesized compounds were evaluated for antimicrobial activities
通过将β-内酰胺醛作为双极性亲和剂衍生的烯基酯与1衍生的偶极偶氮甲meth叶立德的1,3-偶极环加成反应,可以轻松,一锅地合成一系列带有β-内酰胺取代基的新型螺吡咯烷/吡咯并核苷,2-和1,3-二酮和仲氨基酸。评价合成化合物的抗菌活性,发现在较低浓度下对四种人类细菌病原体表现出相对较好的抗菌活性。
