Conversion of amines to imines employing Polymer-Supported Sulfoxide (PSS) and Polymer-Supported Perruthenate (PSP): Synthesis of pyrrolo[2,1-c][1,4] benzodiazepines
An efficient method for the oxidation of secondary amines to the corresponding imines has been developed by employing polymer-supported reagents. This protocol has been extended for the generation of a combinatorial library of substituted pyrrolo[2,1-c][1,4]benzodiazepine derivatives and provides a rapid and clean preparation avoiding conventional purification techniques.
