Construction of the 1,5-Benzodiazepine Skeleton from <i>o</i>-Phenylendiamine and Propargylic Alcohols via a Domino Gold-Catalyzed Hydroamination/Cyclization Process
The gold-catalyzed reaction of o-phenylendiamine with propargylic alcohols affords 1,5-benzodiazepines bearing different substituents on the 2 and 4 positions. The method allows even for the selective preparation of 4-substituted 1,5-benzodiazepine derivatives.

Abstract A novel and simple ionic liquid methodology for the synthesis of 1,5‐benzodiazepines is described. 1‐Butylpyridinium hydrogen sulphate ([BPy]HSO4), an acidic room‐temperature ionic liquid, as a novel and efficient catalyst, was synthesized and used in the preparation of a series of 1,5‐benzodiazepine derivatives by the reaction of o‐phenylenediamine with chalcones under mild conditions. This
apicoplast in the survival of the parasite. In this study, we present the rational design strategy employing sustainable catalysis for the synthesis of benzodiazepine (BDZ) conformers followed by their biological evaluation as prospective inhibitors against the potential target of the IPP pathway, 1-deoxy-D-xylulose-5-phosphatereductoisomerase (DXR). The study reported the inhibitory profile of 8c and 6d
