The construction of CN bonds was achieved by the dehydrogenative coupling of alcohol and azide via aza-Wittig type reaction. The reaction is catalyzed by an acridine-derived ruthenium pincer complex and does not use any oxidant. The present protocol offers a wide substrate scope, including aliphatic, aryl or heteroaryl alcohol/azides. This expeditious protocol was successfully applied to construct a CC bond directly from alcohol via dehydrogenative Wittig reaction. Furthermore, the synthesis of structurally important pyrrolo[1,4]benzodiazepine derivatives was also achieved by this methodology.

Polymer-supported reagents have been utilized for the generation of combinatorial library of substituted pyrrolo[2,1-c][1,4]benzodiazepine derivatives that provides a clean and efficient preparation and does not require conventional purification techniques like chromatography. This methodology involves intra molecular aza-Wittig reaction and has been extended for the synthesis of the natural product DC-81 in good overall yields.

A new and efficient synthesis of the pyrrolo[2,1-c][1,4]benzodiazepine ring system has been carried out using, as a key step, an intramolecular aza-Wittig reaction of the appropriately substituted N-(2-azidobenzoyl)pyrrolidine-2-carboxaldehydes. The paren
