Abstract

Abstract: Biradical(5) were formed by photoinduced single electron transfer of N-phthalimido dipeptide(1) under irradiation.The biradical(5) could couple intramolecularly to form cycloproduct(2) containing ketonpiprazine moiety.This good yield reaction could be used as a new synthesis method for ketonpiperazine analogous.The structures of all the new compounds were characterized by MS and NMR spectra.

Key words: dipeptide, single electron transfer(SET), cyclization reaction, ketopiprazine
