The solid phase synthesis of N-substituted succinimides is described. The s
trategy used is based on the intramolecular cyclization of a dipeptide cont
aining aspartic acid in the second position promoted by diphenylphosphoryla
zide (DPPA) and triethylamine. Large numbers of succinimides can be prepare
d using different, commercially available building blocks. (C) 2000 Elsevie
