New chiral mono- and bicyclic β-sultams, valuable building blocks for drug synthesis, have been prepared from L-Ala, L-Val, L-Leu, L-Ile, L-Phe, L-Cys, L-Ser, L-Thr, and D-penicillamine by transformation of the COOH group into a methylsulfonyl chloride function, followed by cyclization under basic conditions. Selected properties, derivatives, and reactions of the β-sultams are described.

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.
