 note = {The syntheses of the title compounds from the reactions of 2-amino-3-(arylcarbonyl)indolizine-1-carbonitriles with various acetophenones in the presence of strong base were investigated. When the reactions were carried out between 2-aminoindolizines and 1.2-equimolar amounts of acetophenones, the yields for the target molecules were low or very low. However, when a large excess of acetophenones were used without any solvent or in as small as amount of solvent as possible, their yields were considerably improved. The smooth hydrolysis of the 10-cyano group to the carbamoyl one was also observed., Article, HETEROCYCLES. 77(1): 471-481 (2009)},
