A series of N-(1-methyl-1H-indol-3-yl)methyleneamines and eight new 3,3-diaryl-4-(1-methyl-1H-indol-3-yl)azetidin-2-ones have been synthesized and screened for their antileishmanial activity against Leishmania major. 3,3-Diaryl-4-(1-methyl-1H-indol-3-yl)azetidin-2-ones have been synthesized by the Staudinger's ketene-imine cycloaddition employing two 2-diazo-1,2-diarylethanones as the precursors of diarylketenes. A marked improvement in anti-parasitic activity is observed by transformation of the methyleneamines to azetidin-2-ones in seven out of eight compounds. Two compounds displayed antileishmanial activity comparable to that of the clinically used antileshmanial drug, amphotericine B. (C) 2012 Elsevier Ltd. All rights reserved.

alkyl and aromatic amines in ethanol without using any catalyst or dehydrating agent. The compounds have been screened for their antibacterial, antifungal, crown gall tumor inhibitory, and cytotoxic activities. As a major finding some of the compounds exhibited potential biological activity. The imine containing a 4-chlorophenyl group exhibits potential antitumor activity and brine shrimp lethality against

The paper describes the synthesis, characterization data, and biological activity (antibacterial, antifungal, and brineshrimpslethality) of new azetidin‐2‐ones. The compounds have been synthesized by the reaction of diarylketenes, generated in situ from thermal decomposition of the 2‐diazo‐1,2‐diarylethanones, with N‐(1‐methyl‐1H‐indol‐3‐yl)methyleneamines. The compounds have been characterized by
