11beta-Hydroxysteroid dehydrogenase type 1 (11beta-HSD1) has been widely considered by the pharmaceutical industry as a target to treat metabolic syndrome in type II diabetics. We hypothesized that central nervous system (CNS) penetration might be required to see efficacy. Starting from a previously reported pyrimidine compound, we removed hydrogen-bond donors to yield 3, which had modest CNS penetration. More significant progress was achieved by changing the core to give 40, which combines good potency and CNS penetration. Compound 40 was dosed to diet-induced obese (DIO) mice and gave excellent target engagement in the liver and high free exposures of drug, both peripherally and in the CNS. However, no body weight reduction or effects on glucose or insulin were observed in this model. Similar data were obtained with a structurally diverse thiazole compound 51. This work casts doubt on the hypothesis that localized tissue modulation of 11beta-HSD1 activity alleviates metabolic syndrome.

Tetra-O-benzylglucose 1 and trichloroacetonitrile afford in a base catalyzed, fast, and reversible reaction the beta-O-glycosyl imidate 3-beta, which is transformed slowly into the alpha-isomer 3-alpha.Both results, the reactivity differences of 2alpha,beta and the stability differences of 3-alpha/beta are due to lone pair repulsions implicated in the anomeric effect.

The transformation of simple hydrocarbons into more complex and valuable products has revolutionised modern synthetic chemistry. This type of reactivity has quickly become one of the cornerstones of modern catalysis . 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, molecular formula is C12H22O11.

Four mixed-ligand complexes, cis-Rh[(bipy)(HDPA)Cl2]Cl (1), cis-[Rh(phen)(HDPA)Cl2]Cl (2), cis-[Rh(bipy)(DPA)Cl2] (3), and cis-[Rh(phen)(DPA)Cl2] (4) (where bipy = 2,2?-bipyridine, phen = 1,10-phenantroline, HDPA = 2,2?-dipyridylamine, and DPA = the deprotonated form of 2,2?-dipyridylamine) have been synthesized and characterized. In slightly acidic solution and at low temperature (77 K), both complexes 1 and 2 show a broad, symmetric and structureless red emission with microsecond lifetime identified as dd* phosphorescence. In slightly basic solution, the deprotonated complexes (3 and 4) exhibit a broad and asymmetric blue emission, showing no vibrational structure with a lifetime in the order of microseconds. Emission of complex 3 reveals a blue shift of 0.81 mum -1 compared to the emission of complex 1 and that of complex 4 shows a blue shift of 0.77 mum-1 with respect to complex 2. Electrochemical data have also been obtained for the four complexes in CH 3CN. There are two reduction peaks observed for both complexes 1 and 2. Each peak is followed by a one-electron reduction at the metal, with an elimination of chloride during each reduction step, which is in consistent with the dd* phosphorescence assignment for the two complexes. For complexes 3 and 4, only a one-electron reduction process occurs at the metal with an elimination of chloride. Based on the luminescence and electrochemical data, the emission of complexes 3 and 4 are assigned as pid* phosphorescence. Results from density functional theory (DFT) calculations provide theoretical evidence in support of this pid* assignments.

The first total synthesis of the boron-containing macrodiolide antibiotic tartrolon B is reported in full detail. Two convergent approaches to the target compound are described, the first of which eventually failed, due to sensitive functionality. In the second, successful route the key step was a stereoselective boron-mediated aldol addition of a bicyclic acetonide protected ketone to a dienealdehyde. In this case the synthesis could be completed without major problems, using a Yamaguchi dimerization macrolactonization endgame.

HPLC of Formula: C5H10O2, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature 2081-44-9, C5H10O2. A document type is Article, introducing its new discovery.

Rate coefficients of reactions of Cl atoms with cyclic ethers, tetrahydropyran (THP), tetrahydrofuran (THF), and dihydrofurans (2,5-DHF and 2,3-DHF) have been measured at 298 K using a relative rate method. The relative rate ratios for THP and THF are 0.80 ± 0.05 and 0.80 ± 0.08, respectively, with n-hexane as the reference molecule. The relative rate ratios for THF and 2,5-DHF with n-pentane as the reference molecule are 0.95 ± 0.07 and 1.73 ± 0.06, respectively, and for 2,5-DHF with 1-butene as reference is 1.38 ± 0.05. The average values of the rate coefficients are (2.52 ± 0.36), (2.50 ± 0.39), and (4.48 ± 0.59) × 10-10 cm3 molecule-1 s-1 for THP, THF, and 2,5-DHF, respectively. The errors quoted here for relative rate ratios are 2sigma of the statistical variation in different sets of experiments. These errors, combined with the reported errors of the reference rate coefficients using the statistical error propagation equation, are the quoted errors for the rate coefficients. In the case of 2,3-DHF, after correcting for the dark reaction with CH3COCl and assuming no interference from other radical reactions, a relative rate ratio of 0.85 ± 0.16 is obtained with respect to cycloheptene, corresponding to a rate coefficient of (4.52 ± 0.99) × 10-10 cm3 molecule-1 s-1. Unlike cyclic hydrocarbons, there is no increase with increasing number of CH2 groups in these cyclic ethers whereas there is an increase in the rate coefficient with unsaturation in the ring. An attempt is also made to correlate the rate coefficients of cyclic hydrocarbons and ethers with the molecular size as well as HOMO energy.

Highly beta-selective glucosylations of glycosyl acceptors having alpha primary hydroxy group with a 6-nitro-2-benzothia-zolyl alpha-glucoside donor 3alpha proceeded smoothly in the presence of a catalytic amount of trifluoromethanesulfonic acid (TfOH) in CH 2Cl2 at -78 C to afford the corresponding glycosides in high yields. With the use of 3alpha, beta-saccharides could be obtained more dominantly than other alpha-glucosyl donors such as thioform- and trichloroacet-imidates or fluoride in the glucosylation under the same conditions. Similarly, highly beta-selective mannosylations of glycosyl acceptors with a 6-nitro-2-benzothiazolyl alpha-mannoside donor 18alpha were carried out smoothly in the presence of a catalytic amount of tetrakis(pentafluorophenyl)boric acid H[B(C6F5) 4] to afford the corresponding disaccharides in good to high yields; 18alpha apparently behaved as a potent donor here for the construction of beta-mannoside linkage. Interestingly, in situ anomerization from 18beta to 18alpha was observed when beta-mannosyl donor 18beta was treated with a catalytic amount of H[B(C6F5)4] in CH 2Cl2.
