title: Synthesis of 10- and 9-membered dilactams derived from aspartic and glutamic acids.
abstract: 9- and 10-membered bridged dipeptides derived from L-aspartic acid and L- or D-glutamic acid were synthesized using aminoacyl incorporation reaction. Key intermediates containing internal pyroglutamyl moiety were prepared via side chain to backbone cyclization of related protected dipeptide derivatives of glutamic acid.
