(Chemical Equation Presented) A series of peptidomimetics based on a γ-turn motif were synthesized using a modular approach, in which N-protected piperidones were reacted with a selection of 2-hydroxyalkyl azides derived from common L-amino acids. Hydrolysis of the initially formed iminium ethers afforded the targeted series of substituted 1,4-diazepin-5-ones.

A number of peptides and modified peptides were synthesized and studied for their ability to reverse electroconvulsive shock-induced amnesia in rodents.A few of these peptides were selected for secondary evaluation in tests of short-term memory in rats and aged rhesus monkeys.A number of the peptides and modified peptides were active in the amnesia reversal test.In selected secondary tests, however, the chosen compounds failed to show significant activity in enhancing memory.New methods for preparing methyleneamino and methyleneoxy isosters of peptides are reportrd.Other modified peptides also included methylenethio, methylenesulfonyl, and ethylene isosteres in place of the normal peptide amide bond.
