摘要

Mild methods for controlled C-and N-alkylation of 3-benzyloxycarbonylpiperazine-2, 5- diones are reported. The benzyloxylcarbonyl substituent can also serve as latent functionality for N-acyliminium ion formation and subsequent trapping enables installation of new carbon and/or heteroatom substituents.
