A direct gamma-regioselective nucleophilic addition of alcohols toward gamma-enolizable alpha,beta-unsaturated aldehydes was developed using a catalytic amount of MeSO3H (30 mol%) and a stoichiometric amount of chloranil (1.0 equiv) as the oxidant. The addition of hexafluoroisopropanol (HFIP) was found to accelerate this cross-dehydrogenative coupling, furnishing diverse alcoholic adducts with high gamma-regio- and E-stereoselectivities.

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.I hope my blog about 214894-89-0 is helpful to your research. Quality Control of 5-(Bromomethyl)-2,3-dihydro-1,4-benzodioxine.

A convenient and practical catalytic method for the preparation of caffeic acid esters is reported. This esterification was carried out with high efficiency in the presence of ytterbium triflate in nitromethane without any other auxiliary reagents. The wide scope of application and especially the higher reactivity and more convenient procedure than previous methods make it a valuable application for the synthesis of caffeic acid esters and other cinnamic acid esters.

N-3-Hydroxylation of pyrimidine-2,4-diones was recently found to yield inhibitors of both HIV-1 reverse transcriptase (RT) and integrase (IN). An extended series of analogues featuring a benzoyl group at the C-6 position of the pyrimidine ring was synthesized. Through biochemical studies it was found that these new analogues are dually active against both RT and IN in low micromolar range. Antiviral assays confirmed that these new inhibitors are active against HIV-1 in cell culture at nanomolar to low micromolar range, further validating 3-hydroxypyrimidine-2,4-diones as a viable scaffold for antiviral development.

Samarium(II) iodide-water-amine reagents have emerged as some of the most powerful reagents (E = -2.8 V) for the reduction of unactivated carboxylic acid derivatives to primary alcohols under single electron transfer conditions, a transformation that had been considered to lie outside the scope of the classic SmI2 reductant for more than 30 years. In this article, we present a detailed mechanistic investigation of the reduction of unactivated esters, carboxylic acids, and amides using SmI2-water-amine reagents, in which we compare the reactivity of three functional groups. The mechanism has been studied using the following: (i) kinetic, (ii) reactivity, (iii) radical clock, and (iv) isotopic labeling experiments. The kinetic data indicate that for the three functional groups all reaction components (SmI2, amine, water) are involved in the rate equation and that the rate of electron transfer is facilitated by base assisted deprotonation of water. Notably, the mechanistic details presented herein indicate that complexation between SmI2, water, and amines can result in a new class of structurally diverse, thermodynamically powerful reductants for efficient electron transfer to a variety of carboxylic acid derivatives. These observations will have important implications for the design and optimization of new processes involving Sm(II)-reduction of ketyl radicals. (Chemical Equation Presented).

Aryl chlorides in the presence of Pd/C catalyst and NaF react with primary alcohols to form esters, arenes, and alkanes. In this reaction, aryl chlorides act as both oxidants and coupling partners, whereas alcohols serve as both carbonyl sources and alkoxy components of the ester products. (Formula Presented).

The para-fluorinated flexible neurotransmitter analogue 2-phenylethanol has been investigated by highly resolved resonance-enhanced two-photon ionisation two-colour UV laser spectroscopy with mass resolution and ab initio structural optimisations and energy calculations. Two stable conformations, gauche and anti, separated by a high potential barrier have been identified in the cold molecular beam by rotational analysis of the vibronic band structures. The theoretically predicted higher-lying conformations most likely relax to these two structures during the adiabatic expansion. The lowest-energy gauche conformer is stabilised by an intramolecular nonconventional OH…pi-type hydrogen bond between the terminal OH group of the side chain and the pi electrons of the phenyl ring. The good agreement between the experimental and theoretical results demonstrates that even the substitution with a strongly electronegative atom of 2-phenylethanol at the para position has no noticeable effect on the strength and orientation of the OH…pi bond. the Owner Societies.

Ionic hydrogenation has not been extensively explored, but is advantageous for challenging substrates such as unsaturated intermediates. Reported here is an iridium-catalyzed hydrogenation of oxocarbenium ions to afford chiral isochromans with high enantioselectivities. A variety of functionalities are compatible with this catalytic system. In the presence of a catalytic amount of the Br°nsted acid HCl, an alpha-chloroether is generated in situ and subsequentially reduced. Kinetic studies suggest first-order kinetics in the substrate and half-order kinetics in the catalyst. A positive nonlinear effect, together with the half kinetic order, revealed a dimerization of the catalyst. Possible reaction pathways based on the monomeric iridium catalyst were proposed and DFT computational studies revealed an ionic hydrogenation pathway. Chloride abstraction and the cleavage of dihydrogen occur in the same step.
