Acylation of o-Phenylenediamine with 4-Cyclohexene-1,2-dicarboxylic Anhydride

Acylation of o-phenylenediamine with cis- and trans-4-cyclohexene-1,2-dicarboxylic anhydrides in acetone yields cis- and trans-3-(o-aminophenylaminocarbonyl)-4-cyclohexenecarboxylic acids which undergo intramolecular ring closure on heating in o-xylene or petroleum ether to form cis-N-(o-aminophenyl)-4-cyclohexene-1,2-dicarboximide. Heating of 3-(o-aminophenylaminocarbonyl)-4-cyclohexenecarboxylic acid in benzene in the presence of KU-2 cation exchanger (H form) leads to formation of a mixture of cis-N-(o-aminophenyl)-4-cyclohexene-1,2-dicarboximide and 6-(2-benzimidazolyl)-3-cyclohexenecarboxylic acid.

Dibromotriphenylphosphorane Promoted Synthesis of Condensed Heterocyclic Systems from Aromatic Diamines

A new and rather widely applicable method for the synthesis of a number of tri, tetra-, and pentacyclic compounds from ortho-aminodiacylarylimides and dibromotriphenylphosphorane via an intramolecular cyclization is reported.A mechanism for this cyclizati
