Abstract

We describe two routes for the synthesis of a trisubstituted 1, 2, 5-hexahydro-3-oxo-1 H-1, 4- diazepine ring (DAP), a novel, conformationally constrained, seven-membered dipeptidomimetic ring system. The linear precursor for the model DAPs, targeted for conformational analysis studies, was obtained by reductive alkylation of tert-butyl alaninate or phenylalaninate by N-Boc-α-amino-γ-oxo-N, N-dimethylbutyramide. Acetylation of the ...
