Abstract

The reaction of 2-(2-benzimidazolyl)acetonitrile with 3-(2-hydroxyaryl)propenones (2) in the presence of three equivalents of bases afforded the titled ring systems. When 2-(2-benzothiazolyl)acetonitrile was used instead of 2-(2-benzimidazolyl)acetonitrile the reaction afforded the 2-(benzopyran-3-yl)benzothiazole (9).
