Synthesis of Chiral 3,4‐Disubstituted Pyrrolidines with Antibacterial Properties

Chiral aliphatic heterocycles are important structural feature of many pharmaceutical agents. Antibiotic resistance is a serious medical problem, therefore new antibacterial compounds are urgently needed. Herein, we describe synthesis of a series of 3,4‐disubstituted pyrrolidine derivatives via organocatalytic Michael addition followed by reductive cyclization. These compounds inhibited growth of standard as well as methicillin‐resistant strains of Escherichia coli and Staphylococcus aureus .
