Herein, the first-generation process to manufacture Akt inhibitor Ipatasertib through a late-stage convergent coupling of two challenging chiral components on multikilogram scale is described. The first of the two key components is a trans-substituted cyclopentylpyrimidine compound that contains both a methyl stereocenter, which is ultimately derived from the enzymatic resolution of a simple triester starting material, and an adjacent hydroxyl group, which is installed through an asymmetric reduction of the corresponding cyclopentylpyrimidine ketone substrate. A carbonylative esterification and subsequent Dieckmann cyclization sequence was developed to forge the cyclopentane ring in the target. The second key chiral component, a beta2-amino acid, is produced using an asymmetric aminomethylation (Mannich) reaction. The two chiral intermediates are then coupled in a three-stage endgame process to complete the assembly of Ipatasertib, which is isolated as a stable mono-HCl salt.

SAR studies of the substitution effect on the central phenyl ring of the biphenyl scaffold were carried out using anacetrapib (9a) as the benchmark. The results revealed that the new analogs with substitutions to replace trifluoromethyl (9a) had a significant impact on CETP inhibition in vitro. In fact, analogs with some small groups were as potent or more potent than the CF3 derivative for CETP inhibition. Five of these new analogs raised HDL-C significantly (>20 mg/dL). None of them however was better than anacetrapib in vivo. The synthesis and biological evaluation of these CETP inhibitors are described.

In a recent study, we have shown by NMR spectrocopy that monoalkylcarbonates are formed in substantial amounts in aqueous solutions of the tertiary alkanolamine methyldiethanolamine (MDEA) upon loading with carbon dioxide (CO2). These species had been overlooked by most authors previously. In the present work, this study was extended to the primary alkanolamine monoethanolamine (MEA). Also here monoalkylcarbonates were found, but only at CO2 loadings above 0.5 mol CO2 per mol MEA. Both the amine and its carbamate form monoalkylcarbonates. The concentration of the monoalkylcarbonates was determined with 13C NMR spectroscopy in a wide range of CO2 loadings, MEA concentrations, and temperatures. Based on this comprehensive data the chemical equilibirium constants of the formation of the monoalkylcarbonates were determined.

The effect of tethering a thioether to a rhodium(II) paddlewheel complex are evaluated in Si?H insertion reactions. This study provides further evidence for the benefits of incorporating thioethers into the rhodium paddlewheel motif. When using a tethered complex, the in situ carbenoid formation and subsequent Si?H insertion are not impeded, yields are improved by up to 12 % at elevated temperatures, and selectivity for diazo compounds is greater when compared to non-tethered catalysts. Computational modelling of the complexes is also presented in order to rationalize the results.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Leukotriene biosynthesis inhibitors have potential as new therapies for asthma and inflammatory diseases. The recently disclosed thiopyrano[2,3,4- cd]indole class of 5-lipoxygenase (5-LO) inhibitors has been investigated with particular emphasis on the side chain bearing the acidic functionality. The SAR studies have shown that the inclusion of a heteroatom (O or S) in conjunction with an alpha-ethyl substituted acid leads to inhibitors of improved potency. The most potent inhibitor prepared contains a 2-ethoxybutanoic acid side chain. This compound, 14d (2-[2-[1-(4-chlorobenzyl)-4-methyl-6-[(5- phenylpyridin-2-yl)methoxy]-4,5-dihydro-1H-thiopyrano[2,3,4-cd]indol-2- yl]ethoxy]butanoic acid, L-699,333), inhibits 5-HPETE production by human 5- LO and LTB4 biosynthesis by human PMN leukocytes and human whole blood (IC50s of 22 nM, 7 nM and 3.8 muM, respectively). The racemic acid 14d has been shown to be functionally active in a rat pleurisy model (inhibition of LTB4, ED50 = 0.65 mg/kg, 6 h pretreatment) and in the hyperreactive rat model of antigen-induced dyspnea (50% inhibition at 2 and 4 h pretreatment; 0.5 mg/kg po). In addition, 14d shows excellent functional activity against antigen-induced bronchoconstriction in the conscious squirrel monkey [89% inhibition of the increase in R(L) and 68% inhibition in the decrease in C(dyn) (0.1 mg/kg, n = 3)] and in the conscious sheep models of asthma (iv infusion at 2.5 mug/kg/min). Acid 14d is highly selective as an inhibitor of 5-LO activity when compared to the inhibition of human 15-LO, porcine 12-LO and ram seminal vesicle cyclooxygenase (IC50 > 5 muM) or competition in a FLAP binding assay (IC50 > 10 muM). Resolution of 14d affords 14g, the most potent diastereomer, which inhibits the 5-HPETE production of human 5-LO and LTB4 biosynthesis of human PMN leukocytes and human whole blood with IC50s of 8 nM, 4 nM, and 1 muM respectively. The in vitro and in vivo profile of 14d is comparable to that of MK-0591, which has showed biochemical efficacy in inhibiting ex vivo LTB4 biosynthesis and urinary LTE4 excretion in clinical trials.

alpha-N-Acylamino acids have been developed as useful reagents for the preparation of optically pure alpha-aminoalkylaryl ketones.Protection of the amino group as either the ethoxycarbonyl or benzenesulfonyl derivative allows alanine to serve as an effective educt for the chirally specific synthesis of a variety of structures containing the phenylethylamine backbone.Benzene undergoes Friedel-Crafts acylation with the N-acylalanine acid chloride.Catalyst complexation with oxagenated aromatics, however, prohibits acylation of aryl ethers.An arylmetallo reaction scheme overcomes this problem and also affords regiospecificity not attainable in conventional acylations.As examples, optically pure ephedrines and amphetamines were directly synthesized without recourse to resolution since the chirality of the amino acid educt was entirely conserved throughout the process.

Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Read on for other articles about 16251-45-9

Qualitative and quantitative NMR experiments were performed on 5M aqueous solutions of monoethanolamine (MEA) loaded with CO2 (alpha = 0.4) and in presence of 1mM FeSO4 x 7H2O as a catalyst. The main degradation products were identified and quantified by 1D and 2D NMR Spectroscopy as: N-(2-hydroxyethyl) imidazole (HEI), 2-oxazolidone (OZD), N-(2-hydroxyethyl) formamide (HEF). There are also some other signals not quantified yet because of the low intensity. The NMR results were compared with GC/LC-MS results of the same solution.
