Opis:: Various ketene dithioacetals of acetoacetanilides were reacted with guanidine nitrate in the presence of base to produce the 2-amino-4-isopropyl-6-alkoxy-N-arylpyrimidine-5-carboxamide derivatives with good yields. All the synthesized compounds were characterized by mass, NMR and IR and also evaluated for antimicrobial activity against five different bacterial and fungal strains. The compounds 4i, 4k and 4l has found comparatively good active against all the bacterial strains.

Opis:: A series of Schiff derivatives (5a-q) and azetidinone by way of amide linkage analogues (6a-q) containing 2-amino benzthiazole have been synthesized. Amide linkage were adapted from acid via reaction with hydrazine hydrate followed by reaction with different substituted aldehyde derived various Arylidene derivatives comprising with various donor and acceptor functional group. The structures of the new synthesized azetidinone derivatives were characterized on the basis of 1H-NMR, Mass, IR and elemental analysis data.
