Heterocyclic Compounds from Schiff's Bases

Synthesis, Characterization, Biological Evaluation and Anti Corrosion Activity of Some Heterocyclic Compounds Oxazepine Derivatives from Schiff Bases

A series of Schiff base and their derivative (oxazepine) have been synthesized. 1, 4-Bis (3-aminopropyl)piperazine was condensed with various aromatic aldehyde in ethanol in the presence of acetic acid as catalyst to yield the Schiff bases. These Schiff’s bases on treatment with phthalic anhydride gave substituted oxazepine. The structure of synthesized Schiff bases has been established on the ...

Recent heterocyclic compounds from marine invertebrates: Structure and synthesis

A large variety of unique heterocyclic natural marine products, without terrestrial counterparts, have been isolated from marine invertebrates, mainly sponges, ascidians, and soft corals. Many of these compounds display interesting biological activity. In this review, we report our recent studies on nitrogen-containing heterocyclic compounds (“alkaloids”), as well as some containing sulfur and ...

Synthesis of Some New Heterocyclic Compounds with Potential Biological Activity

A series of new 2-arylimino-3-aryl-5-[5?-(3,4-dichlorophenyl)-2?-furylidene]-4-thiazolidinones (3a-l) have been synthesised by the condensation of 5-(3,4-dichlorophenyl)-2-furaldehyde 1 with 2-arylimino-3-aryl-5H-4-thiazolidinones 2 in glacial acetic acid. The physical and spectral data of the synthesised compounds are determined. The synthesised compounds have been screened for their in vitro ...
