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.
