Saccharide recognition-induced transformation of pyridine-pyridone alternate oligomers from self-dimer to helical complex

(Chemical Equation Presented) Co-oligomers involving (1H)-4-pyridone and 4-alkoxypyridine rings were studied, and it was found that their supramolecular transformation was caused by saccharide recognition. In the co-oligomers, pyridone and pyridine rings are alternately linked at their 2,6-position with an acetylene bond. The pyridine rings behave as a hydrogen bonding acceptor, and the pyridone rings and tautomerized 4-pyridinol work as a donor. Pyridine-pyridone-pyridine 3-mer was found to self-dimerize on the basis of vapor pressure osmometry in CHCl3, and the association constant was obtained as 2.3 ¡Á 103 M-1 by 1H NMR titration. Longer 5-, 7-, 9-, and 11-mer oligomers showed considerable broadening and anisotropy in the 1H NMR spectra due to self-association. These longer oligomers recognized octyl beta-D- glucopyranoside and changed their form into a chiral helical complex, showing characteristic circular dichroism.

PROCESS FOR PRODUCTION OF OPTICALLY ACTIVE HYDROXYMETHYLATED COMPOUNDS

The present invention presents a catalyst that allows asymmetric hydroxymethylation reactions to progress with excellent asymmetric selectivity and a production method for optically active hydroxymethylated compounds using the catalyst. Optically active hydroxymethylated compounds are obtained with excellent asymmetric selectivity by using a catalyst obtained by mixing chiral ligands (for example, chemical formula 4) with scandium triflate and the like.

New efficient method for the synthesis of chiral 2,2?-bipyridyl ligands

An efficient preparation of chiral 2,2?-bipyridines was developed. Compound 1 was synthesized in 54% yield for three steps starting from 2,6-dibromopyridine. In this synthesis, only catalytic amounts of metals were used in the asymmetric reduction and homo-coupling reaction steps. The total yield and simplicity of experimental procedures were much improved compared with those of the previous report. Other chiral 2,2?-bipyridines were similarly synthesized with high efficiency.

4-Aminoquinolone piperidine amides: Noncovalent inhibitors of DprE1 with long residence time and potent antimycobacterial activity

4-Aminoquinolone piperidine amides (AQs) were identified as a novel scaffold starting from a whole cell screen, with potent cidality on Mycobacterium tuberculosis (Mtb). Evaluation of the minimum inhibitory concentrations, followed by whole genome sequencing of mutants raised against AQs, identified decaprenylphosphoryl-beta-d-ribose 2?-epimerase (DprE1) as the primary target responsible for the antitubercular activity. Mass spectrometry and enzyme kinetic studies indicated that AQs are noncovalent, reversible inhibitors of DprE1 with slow on rates and long residence times of ?100 min on the enzyme. In general, AQs have excellent leadlike properties and good in vitro secondary pharmacology profile. Although the scaffold started off as a single active compound with moderate potency from the whole cell screen, structure-activity relationship optimization of the scaffold led to compounds with potent DprE1 inhibition (IC50 < 10 nM) along with potent cellular activity (MIC = 60 nM) against Mtb. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. 875-66-1, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 875-66-1, in my other articles.

SOME REACTIONS OF 3-HALOGENOCINNOLINES CATALYSED BY PALLADIUM COMPOUNDS

3-Bromo-or 3-iodo-cinnoline (and 4-substituted analogues ) are condensed with terminal alkynes in the presence of Pd and Cu compounds as catalysts to give the 3-alkynyl-derivatives.When 4-chloro- or 4-phenoxy-compounds are used, the products react with amines, in the presence of copper(I) iodide, to form pyrrolo<3,2-c>cinnolines and with hydrazines to give either the same ring system or a pyrazolo<4,3-c>cinnoline.Hydrolysis of 3-alkynyl-4phenoxycinnoline to 3-alkynyl-4(1H)-cinnolinone, followed by cyclisation, yields the furo<3,2-c>cinnoline.Attempts to condense 3-halogenocinnolines with alkenes gave variable results: 3-phenyl ethenyl- and 3(2-pyridylethenyl)-4-(1H)-cinnolinones were obtained but 3-bromocinnoline gave the 3,3′-bicinnolinyl.Action of palladium acetate in the presence of ethyl acrylate converted 3-bromo-4-phenoxycinnoline into benzofuro<3,2-c>cinnoline and 3-bromo-4-phenylaminocinnoline into indolo<3,2-c>cinnoline.
