Design and synthesis of dual peroxisome proliferator-activated receptors gamma and delta agonists as novel euglycemic agents with a reduced weight gain profile

The design and synthesis of the dual peroxisome proliferator-activated receptor (PPAR) gamma/delta agonist (R)-3-{4-[3-(4-chloro-2-phenoxy-phenoxy) -butoxy]-2-ethyl-phenyl}-propionic acid (20) for the treatment of type 2 diabetes and associated dyslipidemia is described. The compound possesses a potent dual hPPAR gamma/delta agonist profile (IC50 = 19 nM/4 nM; EC50 = 102 nM/6 nM for hPPARgamma and hPPARdelta, respectively). In preclinical models, the compound improves insulin sensitivity and reverses diabetic hyperglycemia with less weight gain at a given level of glucose control relative to rosiglitazone.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Reference of 24621-61-2. I hope my blog about 24621-61-2 is helpful to your research.

Stereocontrolled synthesis of 1,5-stereogenic centers through three-carbon homologation of boronic esters

Allylic pinacol boronic esters are stable toward 1,3-borotropic rearrangement. We developed a PdII-mediated isomerization process that gives di- or trisubstituted allylic boronic esters with high E selectivity. The combination of this method with lithiation-borylation enables the synthesis of carbon chains that bear 1,5-stereogenic centers. The utility of this method has been demonstrated in a formal synthesis of (+)-jasplakinolide. Three more: The 3C homologation of chiral pinacol boronic esters gives di- or trisubstituted allylic boronic esters with high yield and E selectivities. The combination of this method with lithiation-borylation enables the synthesis of alkyl chains that bear 1,5-stereogenic centers. The utility of the process was demonstrated in a formal synthesis of (+)-jasplakinolide.

A homogeneous catalyst for reduction of optically active esters to the corresponding chiral alcohols without loss of optical purities

A ruthenium complex was found to catalyze the hydrogen reduction of esters under mild and neutral conditions. A variety of optically active esters can be reduced to the corresponding alcohols in excellent yield without loss of their optical purity or causing undesirable side reactions. Hydrogen reduction needs such simple operations – reaction, concentration, and purification – that the violent quench step and extraction step, which accompany conventional sodium borohydride or lithium aluminum hydride reduction, can be omitted.

Convenient synthesis of anionic dinuclear ruthenium(II) complexes [NR2H2][{RuCl(diphosphine)}2(mu-Cl) 3] [diphosphine = 2,2?-bis(diphenylphosphino)-1,1?-binaphthyl, 2,2?-bis(di(p-tolyl)phosphino)-1,1?-binaphthyl, and 1,2-bis(diphenylphosphino)benzene]:

We report a practical one-pot synthesis of dialkylammonium salts of anionic dinuclear ruthenium complexes having chelating diphosphine ligands, BINAPs and DPB, with formula of [NEt2H2][{RuCl(diphosphine)}2(mu-Cl) 3] [2a: diphosphine = 2,2?-bis-(diphenylphosphino)-1,1?-binaphthyl; 6a: 2,2?-bis(di(p-tolyl)phosphino)-1,1?-binaphthyl; 8a: 1,2-bis(diphenylphosphino)benzene]. Treatment of cationic ruthenium complexes, [RuCl(eta6-p-cymene)(diphosphine)]Cl (4) with a slight excess of NEt2H2Cl (5a) afforded 2a, 6a, and 8a in quantitative yields. Similar reactions with various dialkylammonium salts 5b-f gave the corresponding salts, [NR2H2][{RuCl(diphosphine)}2(mu-Cl) 3]. A one-pot mixture of BINAP or its derivative, [RuCl2(eta6-arene)]2, and NR2H2Cl produced salts of the anionic dinuclear complexes which can be applied as catalysts for the asymmetric hydrogenation of ketonic substrates such as acetol and methyl acetoacetate with high activity and high enantioselectivity. The anionic face-sharing bioctahedral structure of these complexes was confirmed by the X-ray analysis of 8a, which has two hydrogen bonds between two NH of the diethylammonium cation and two terminal chloro-ligands.

Rhodotorula minuta-mediated bioreduction of 1,2-diketones

The reduction of cyclic and acyclic 1,2-diketones was investigated by employing whole cells of the yeast Rhodotorula minuta as biocatalyst. The reactions showed a variable degree of regio- and enantioselectivity depending on the nature of the substrate. In the case of cyclic diketones, the reduction afforded a mixture of diastereomeric diols only. The reduction of acyclic diketones allowed production of both the hydroxy ketone and the diol, in a two-step reaction. The first step was highly regio- and stereoselective, affording the hydroxy ketone of (S)-configuration with high enantiomeric excess. After longer reaction times the corresponding (S,S)-diols were obtained in high yield and diastereomeric excess.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about19132-06-0.name: (2S,3S)-Butane-2,3-diol

A chemical/computational approach to the determination of absolute configuration of flexible and transparent molecules: Aliphatic diols as a case study

(Graph Presented) By reacting flexible and optically transparent in UV-vis molecules such as 1,2-, syn- and anti-1,3-diols, 1,3-sulfanylalcohols of known absolute configuration (AC) with fluorenone dimethyl acetal, the corresponding ketals are obtained. They are conformationally well-defined (only one conformer in most cases) compounds exhibiting medium-high optical rotation (OR) values, which are independent of the solvent, and electronic circular dichroism (ECD) spectra, which show several (up to five) Cotton effects in the 350-200 nm range due to valence shell pi?pi* transitions. These features allow simulation of the chiroptical properties of these compounds at the TDDFT/B3LYP/6-31G* level of theory to obtain, using the known ACs of these compounds, a satisfactory reproduction of the OR values (sign and order of magnitude; quantitatively, the predicted values are twice the experimental ones), and a more than satisfactory reproduction of the ECD spectra (sign, intensity, and position of the lowest-energy four Cotton effects) for all the compounds studied. Therefore, this approach can be used to assign the AC of such flexible molecules, in particular, syn-1,3-diols, which are important substrates in organic synthesis and for which nonempirical methods of AC assignment have not been devised so far. Furthermore, since the fluorene chromophore leads to the presence of several Cotton effects from, say, 350 to 200 nm, their correct simulation of sign, intensity, and position is a guarantee of the correct assignment of AC: in this way, ECD spectroscopy gains the same advantages of VCD spectroscopy, that is, the need of reproducing many ECD bands and then a solid guarantee of a correct AC assignment.

Asymmetric Induction by a Nitrogen14N/15N Isotopomer in Conjunction with Asymmetric Autocatalysis

Chirality arising from isotope substitution, especially with atoms heavier than the hydrogen isotopes, is usually not considered a source of chirality in a chemical reaction. An N2,N2,N3,N3-tetramethyl-2,3-butanediamine containing nitrogen (14N/15N) isotope chirality was synthesized and it was revealed that this isotopically chiral diamine compound acts as a chiral initiator for asymmetric autocatalysis.
