Asymmetric addition of chiral triquinphosphoranes on activated carbonyl compounds

Chiral triquinphosphoranes react with trifluoroacetophenone, ketopantolactone and aromatic aldehydes affording pairs of hydroxyphosphoranes diastereomers with a diastereoselectivity up to 90% depending on the nature of the electrophile. In the case of ketopantolactone, hydroxyphosphorane diastereomers are quantitatively converted to alkoxyphosphoranes with a decreasing of diastereomeric excesses. The major alkoxyphosphorane diastereomer exhibits a close SP structure determined by x-ray diffraction analysis.

Modeling, synthesis, and biological evaluation of potential retinoid X receptor (RXR) selective agonists: Novel analogues of 4-[1-(3,5,5,8,8- Pentamethyl-5,6,7,8-tetrahydro-2-naphthyl)ethynyl]benzoic Acid (Bexarotene) and (E)-3-(3-(1,2,3,4-tetrahydro-1,1,4,4,6-pentamethylnaphthalen-7-yl) -4-hydroxyphenyl)acrylic acid (CD3254)

Three unreported analogues of 4-[1-(3,5,5,8,8-pentamethyl-5-6-7-8- tetrahydro-2-naphthyl)ethynyl]benzoic acid (1), otherwise known as bexarotene, as well as four novel analogues of (E)-3-(3-(1,2,3,4-tetrahydro-1,1,4,4,6- pentamethylnaphthalen-7-yl)-4-hydroxyphenyl)acrylic acid (CD3254), are described and evaluated for their retinoid X receptor (RXR) selective agonism. Compound 1 has FDA approval as a treatment for cutaneous T-cell lymphoma (CTCL), although treatment with 1 can elicit side-effects by disrupting other RXR-heterodimer receptor pathways. Of the seven modeled novel compounds, all analogues stimulate RXR-regulated transcription in mammalian 2 hybrid and RXRE-mediated assays, possess comparable or elevated biological activity based on EC50 profiles, and retain similar or improved apoptotic activity in CTCL assays compared to 1. All novel compounds demonstrate selectivity for RXR and minimal crossover onto the retinoic acid receptor (RAR) compared to all-trans-retinoic acid, with select analogues also reducing inhibition of other RXR-dependent pathways (e.g., VDR-RXR). Our results demonstrate that further improvements in biological potency and selectivity of bexarotene can be achieved through rational drug design.

Evaluation of anthropogenic secondary organic aerosol tracersfrom aromatic hydrocarbons

Products of secondary organic aerosol (SOA) from aromatic volatile organic compounds (VOCs) – 2,3-dihydroxy-4-oxopentanoic acid, dicarboxylic acids, nitromonoaromatics, and furandiones – were evaluated for their potential to serve as anthropogenic SOA tracer5with respect to their (1) ambient concentrations and detectability in PM2:5 in Iowa City, IA, USA; (2) gas-particle partitioning behaviour; and (3) source specificity by way of correlations with primary and secondary source tracersand literature review. A widely used tracer for toluene-derived SOA, 2,3-dihydroxy-4-oxopentanoic acid was only detected in the particle phase (Fp D 1) at low but consistently measurable ambient concentrations (averaging 0.3 ngm-3/. Four aromatic dicarboxylic acids were detected at relatively higher concentrations (9.1-34.5 ngm-3/, of which phthalic acid was the most abundant. Phthalic acid had a low particlephase fraction (Fp D0.26) likely due to quantitation interferences from phthalic anhydride, while 4-methylphthalic acid was predominantly in the particle phase (Fp D 0.82). Phthalic acid and 4-methylphthalic acid were both highly correlated with 2,3-dihydroxy-4-oxopentanoic acid (rsD 0.73, p D 0.003; r5D 0.80, p > 0.001, respectively), suggesting that they were derived from aromatic VOCs. Isophthalic and terephthalic acids, however, were detected only in the particle phase (Fp D 1), and correlations suggested association with primary emission sources. Nitromonoaromatics were dominated by particle-phase concentrations of 4-nitrocatechol (1.6 ngm-3/ and 4-methyl-5-nitrocatechol (1.6 ngm-3/ that were associated with biomass burning. Meanwhile, 4-hydroxy-3-nitrobenzyl alcohol was detected in a lower concentration (0.06 ngm-3/ in the particle phase only (Fp D 1) and is known as a product of toluene photooxidation. Furandiones in the atmosphere have only been attributed to the hotooxidation of aromatic hydrocarbons; however the substantial partitioning toward the gas phase (Fp =0.16) and their water sensitivity limit their application as tracers. The outcome of this study is the demonstration that 2,3-dihydroxy-4-oxopentanoic acid, phthalic acid, 4-methylphthalic acid, and 4-hydroxy-3-nitrobenzyl alcohol are good candidates for tracing SOA from aromatic VOCs.

Optically active tetrahydrofran-2-carboxylic acid manufacturing method (by machine translation)

The present invention provides a method for producing tetrahydrofuran-2-carboxylic acid with high optical activity by using cheap and easy accessible material in industrial. The method for producing optically active tetrahydrofuran-2-carboxylic acid includes reacting a mixture of (R)- and (S)-tetrahydrofuran-2-carboxylic acid with benzylamine, and carrying out crystal precipitation and purification in aliphatic series alcohol with 2 to 4 carbon atoms or mixed solvent of aliphatic series alcohol with 2 to 4 carbon atoms. Thus (R)- or (S)-tetrahydrofuran-2-carboxylic acid with an optical purity larger than 99.0%e.e. is obtained.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C5H8O3, you can also check out more blogs about87392-05-0

CHAPTER 2: Catalytic Processes and Catalyst Development in Biorefining

The great potential of the catalytic biorefinery makes it practical for the substitution of renewable plant biomass for fossil feedstocks in new and traditional technologies. The scientific and commercial interest in the biorefinery concept has grown rapidly in the XXI century. The present Chapter is an overview of prospective catalysts and catalytic processes for valorization of plant biomass. There are three parts in the Chapter. Part 1 is a brief description of the composition and properties of the three most important components of plant biomass (cellulose, hemicelluloses and lignin). Part 2 gives insights into thermochemical and liquid-phase (more details are given in Chapter 3) processes for lignocellulose decomposition to produce bio-products (biochar, bio-oil and biogas) and platform molecules that are capable of replacing fossil raw materials (coal, oil and natural gas). Special emphasis is placed on pyrolysis, liquefaction and gasification, which transform lignocellulose into bio-oil and synthesis gas, as the methods for thermochemical depolymerization. Liquid-phase depolymerization of polysaccharides combined with dehydration, reduction, hydrogenolysis and oxidation in one-pot processes, as well as aqueous-phase reforming and biomass delignification, are discussed. Part 3 describes transformations of the main biomass-derived semi-products (syngas, bio-oil, sugars, furfurals and levulinic acid) to fuels or chemicals. Ready-to-use and promising methods for catalytic and biotechnological upgrading of bio-products to fuels and chemicals are considered.

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