Synthesis and Selective Reactions of v-Triazolo<1,5-b>pyridazinium Salts with Nucleophiles. A Facile Access to Functionalized Ethenyl-1,2,3-triazoles

v-Triazolo<1,5-b>pyridazinium salts 5a-c synthesized from alpha-pyridazinyl ketone arylhydrazones and 2,4,4,6-tetrabromocyclohexa-2,5-dien-1-one (TBB) reacted selectively with nucleophiles to yield – besides substituted derivatives 6 – ring-opened cyano compound 9 and/or v-triazoles containing olefinic side chain 10-12.Mechanistic considerations reveal that cation 5 reacts with nucleophiles predominantly at C-7 unless other positions are especially activated.This selectivity proved to be in good agreement with results of semiempirical quantum chemical calculations.

Chiral oxime ethers in asymmetric synthesis. 3. Asymmetric synthesis of (R)-N-protected alpha-amino acids by the addition of organometallic reagents to the ROPHy oxime of cinnamaldehyde

A new asymmetric synthesis of alpha-amino acids is described in which the key step is the diastereoselective addition of organometallic reagents to (R)-O-(1-phenylbutyl)cinnamaldoxime 5 to give hydroxylamines 6. Subsequent reductive cleavage of the N-O bond in the hydroxylamine 6 followed by N- protection gave the carbamates 7, which upon oxidation with ruthenium(III) chloride/periodate gave the N-protected amino acids 8. The method was also adapted to the synthesis of a quaternary amino acid 15 from the ketoxime ether 9.

Stereoselective Micellar Catalysis. Part 3. Co-operative Effects of N-Decanoyl-L-histidine for the Hydrolysis of Enantiomeric Substrates

The catalytic activities of N-decanoyl-L-histidine (Ia) and its methyl ester (Ib) toward the hydrolyses of enantiomeric substrates (II) have been investigated in the presence of cetyltrimethylammonium bromide micelles.The comparison of catalytic effects (both the rate constants and stereoselectivities) of (Ia) and (Ib) strongly suggests that carboxylate ion of (Ia) intramolecularly enhances the reactivity of the imidazole group.The presence of co-operative effects is also supported by the pH-rate profile and by the thermodynamic parameters of the reaction.

Biological evaluation and molecular docking studies of synthesized 5-substituted-2-chlorophenyl-4-chloro derivatives bearing pyridazinone moiety

Chemical modification of pyridazinone may lead to a potent therapeutic agent. In this study, biological properties of pyridazinone derivatives were evaluated by assessing their antimicrobial and in-vitro antioxidant activities. The reaction of a mucochloric acid and 3-chloro-phenylhydrazine hydrochloride led to the formation of 5-aryl-4-chloro-2-(3-chloro-phenyl)-2H-pyridazin-3-one derivatives 2(a-j). The target compounds were synthesized using nucleophilic substitution reaction. In-silico molecular docking studies of the synthesized compounds were carried out with the help of V-Life Science MDS 4.6 software using GRIP batch docking method to find out which derivative had a better docking. The newly synthesized compounds were characterized by FTIR,1HNMR,13C-NMR, MS, and elemental analysis. Antimicrobial and in-vitro antioxidant activity study of the novel synthesized compounds were screened. Compounds 2f and 2g showed good antimicrobial having an MIC 12.5 mug/mL against Staphylococcus aureus and Candida albicans and in-vitro antioxidant activities having an IC50 50.84. The experimental results were further supported by molecular docking analysis with better interaction patterns.

New reactions of gamma-halocarbanions: Underestimated reactive intermediates in organic synthesis

Short-lived gamma-halocarbanions can be trapped by active electrophiles such as aldehydes, imines, and Michael acceptors to give anionic adducts, which undergo intramolecular substitution to give substituted tetrahydrofurans, pyrrolidines, and cyclopentanes. This has underlain a new method for the synthesis of these valuable ring systems. We have determined the acidity of the gamma-halocarbanion precursors and have shown that the halogen atoms in the gamma-position relative to the carbanion center exert a significant stabilizing effect on the carbanion.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 89089-18-9, help many people in the next few years.name: 3-Bromo-6-chloropyridazine
