Abstract

The structures of the compounds obtained were confirmed by their elemental ana! ysses and IR spectra. The IR spectrum of (IV) and (V) showed absorption for the am• carbonyl groups at 1710" 1690 cm-1; absorption of the ketone carbonyl was shifted to higher frequencies (1725- 1715 cm-1). Absorption for the methyl and methylene groups occurred at 2985-1975 and 2855-2845 cm-I, respectively. The IR spectra of (VI-XXXI) showed absorption typical of ...
