ABSTRACT A series of oxazolone derivatives (1-14) have been synthesized as potential anti
cancer agent. The newly synthesized compounds were evaluated for cytotoxicity in the A549 …

The condensation reaction of 5-Amino-1-N-aryl-1H-1, 2, 3-triazole ethyl ethers with
piperidine-2-one was carried out in 3 steps. Phenyl azide derivatives were obtained in the …

A straight forward synthesis of 4-arylidene-2-phenyl-5 (4H)-oxazolones (also called
azlactones) by the condensation of arylaldehyde with hippuric acid in the presence of acetic …

Mannich reaction is one of the versatile reaction widely used in organic synthesis. This
reaction is useful for synthesizing N-methyl derivatives and many drug molecules. Mannich …

This study includes synthesis of some nitrogenous heterocyclic compounds linked to amino
acid esters or heterocyclic amines that may have a potential activity as antimicrobial and/or …

Objectives: Using different activated heterocyclic amines to prepare diazonium salts to be
coupled with ornidazole (heterocyclic agent) to form the azo linkage compounds (A1, A2) as …

The study is on the synthesis, characterization and antimicrobial activities of 1-ethyl-2-methyl-
4-nitroimidazole-5-thiol and its derivatives. 5-chloro-1-ethyl-2-methylimidazole (2) was …

ABSTRACT Geometry optimization calculations for 5, 5-((Pentane-2, 4-Diylidene bis (-1-yl-
1Yalideneazan)) bis (1, 3, 4-Thiadazole-2-thiol), B, is carried out to establish a direct …

Schiff bases (Sh1-Sh3) have been synthesized (p-aminophenol) was condensed with
different aromatic aldehyde in ethanol inthe presence of glacial acetic acid as catalyst …
