Abstract
The invention provides a method of synthesizing N-substituted 1,4-piperazines and N-substituted 1,4-piperazinediones. The invention also provides a method for synthesing combinatorial libraries of piperazine derivatives which can be assayed for biological activity in pre-specified ligand binding or enzymatic activity screens.
