Abstract
An efficient solid‐phase synthetic method for 2,3,4,5‐Tetrahydro‐1,4‐benzodiazepin‐2,5‐diones, having amine derivatives on the benzene ring, was developed. This method has been successfully applied to the synthesis of several spatially separated drug‐like and information‐rich small‐molecule libraries composed of 400 compounds using ACT‐496 automatic synthesizer and the IRORI radio frequency‐encoded split‐mix synthesis technology.
