A Fast and Efficient Method for the Synthesis of 1,5-Benzodiazepine Derivatives Under Solvent-Free Conditions
Authors
Abstract:
Silica sulfuric acid is found to catalyze efficiently the condensation of o-phenylenediamines with various linear and cyclic ketones to afford the corresponding 1,5-benzodiazepines in quantitative yields under solvent-free conditions at room temperature
