Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Anwer, Kurls E., once mentioned the application of 96-49-1, Name is Ethylene carbonate, molecular formula is C3H4O3, molecular weight is 88.06, MDL number is MFCD00005382, category is naphthyridine. Now introduce a scientific discovery about this category, Recommanded Product: Ethylene carbonate.
Conventional and Microwave Synthesis of Some New Pyridine Derivatives and Evaluation Their Antimicrobial and Cytotoxic Activities
THE NEWLY synthesized compounds based on 2-amino-6-(2,4-dimethoxyphenyl)-4-(4-methoxyphenyl)nicotinonitrile 1. The reactivity of pyridine derivative 1 was studied towards different reagents by its reaction with malononitrile, 2-(4-chlorobenzylidene) malononitrile, ethyl cyanoacetate, cyano acetic acid, m-nitro benzaldehyde, sodium azide, formamide, acetic anhydride and/or acetic anhydride/H2SO4 to give compounds 2-5,7, 10-13, respectively. The reaction of 5 with acetyl acetone gave the bipyridine derivative 6, while reaction of compound 7 with chloroacetyl chloride and phenacyl bromide gave the azetidinone derivatives 8 and 9. The formimidate 14 were obtained via reaction of compound 1 with triethylorthoformate, while reaction of 14 with phenylene diamine and/or acetamide gave the formimidamide and pyridopyrimidine derivatives 15 and 16 respectively. Compound 1 was also allowed to react with urea, thiourea, phthalic anhydride, succinic anhydride, benzoyl chloride, chloroacetonitrile, chloroacetyl chloride, p-toluenesulfonylchloride and ethyl bromoacetate to give compounds 17a,b – 24. Reaction of compound 1 with dichloro reagents in 1:1 ratio gave the bicyclic derivatives 25a-c, while its reaction with oxalyl chloride, dichloro and tetrachlorobenzoquinone derivatives, and/or dichloronaphthoquinone gave the imidazopyridine derivatives 26-29. Reaction of compound 29 with o-phenylenediamine in 1:2 ratio afforded the di-condenesed product 30 while, reaction of compound 1 with dichlororeagents in 1:2 ratio gave the polyalkyl derivatives 31a-b. The newly synthesized compounds were characterized by IR, H-1-NMR, C-13-NMR and mass spectra. On the other hand the antimicrobial and anticancer activities of some of the newly synthesized compounds were studied and evaluated.
