Abstract

Diketopiperazine stereoselective [n-15]-isotopic labeling Lactam activation Stereoselective synthesis TRAL
The unexpected reactivity of 2,5-diketopiperazines under basic conditions, thanks to N-Boc activation, allows access to valuable pharmacological scaffolds, such as original statine derivatives. Toward this transannular rearrangement of activated lactams (TRAL), we report here the study of his lactam reactivity using -isotopic labeling. (C) 2007 Elsevier Ltd. All rights reserved.
