Abstract

Methods are proposed for the synthesis of previously unknown pyrido[1,2-a]benzimidazoles via the cyclocondensation of 2-acylmethyl-1H-benzimidazoles with malononitrile, triethylorthoformate ester, or ethoxymethylenemalononitrile.

Keywords

benzimidazoles ethoxymethylenemalononitrile malononitrile pyrido[1,2-a]-benzimidazoles triethylorthoformate ester
