Abstract

Azetidine is a prevalent structural motif found in various biologically active compounds. In this research paper, we report La(OTf)3-catalyzed intramolecular regioselective aminolysis of cis-3,4-epoxy amines to afford azetidines. This reaction proceeded in high yields even in the presence of acid-sensitive and Lewis basic functional groups.

Keywords: Lewis acid; azetidine; catalytic reaction; cyclization; epoxide; regioselectivity; synthetic methods.
