| Abstract: | The reaction of nitriles and of methyl imino ester hydrochlorides of arylsulfonyl(thio)propionic acids with o-phenylenediamine, o-aminophenol, and o-aminothiophenol has been studied. A series of new 2-substituted benzazoles has been synthesized containing arylsulfonyl(thio)propionic acid fragments. |
| Keywords: | benzimidazole benzoxazole benzothiazole imino ester hydrochlorides of carboxylic acids nitriles condensation |
