- Solid-phase synthesis of C-terminal azapeptides
-
The solid-phase synthesis of azapeptides possessing a C-terminal aza-residue has been accomplished by a protocol featuring regioselective alkylation of benzhydrylidene-aza-glycinamide and illustrated by the syntheses of [aza-Lys6] growth-hormone-releasing peptide-6 analogs.

- Cyclization of the semicarbazones to 1,3,4-oxadiazole derivatives using ceric ammonium nitrate as oxidant
-
Cyclization of the semicarbazones to 1,3,4-oxadiazole using ceric ammonium nitrate as oxidant was studied. 2-Imino-1,3,4-oxadiazolines can be produced from semicarbazones, which undergo thermolysis to amides. Benzoic acid benzylidene hydrazide can also be cyclized to 2-methoxy-2-phenyl-1,3,4-oxadiazole in the presence of ceric ammonium nitrate and methanol.
