2,3-Dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) catalyzes the preparation of N-tetrahydropyranylbenzazoles, 2-substituted 1,3-diphenylimidazolidines, and N-(arylmethylene)benzene-1,2-diamines.In the latter case, use of one equivalent of DDQ provides a novel one-pot method for the synthesis of 1H-benzimidazoles.

1H-Benzimidazoles, 1H-imidazopyridines, and 1H-imidazopyridines can be synthesized readily by reaction of unisolated N-(1-chloroalkyl)pyridinium chlorides with 1,2-benzenediamines, 2,3-pyridinediamine, and 3,4-pyridinediamine, respectively.

Reaction of malononitrile, arylidenemalononitrile, chloroacetonitrile or ethyl cyanoacetate with o-aminobenzenethiol, o-aminophenol, 2-aminobenzothiazole, anthranilamide, o-phenylenediamine, p-nitro-o-phenylenediamine, 2-naphthylamine, 2-amino-3-hydroxypyridine or 2,3-diaminopyridine afforded a new series of nitrogen-containing mono- or poly-heterocyclic derivatives via initial addition to either the cyano or the styryl function followed by cyclization.The structure of the obtained products was elucidated by microanalyses, IR and NMR data.
