Synthesis and substance P antagonist activity of naphthimidazolium derivatives

The synthesis of unsymmetrical naphth[2,3-d]imidazolium and bridged naphth[2,3-d]imidazolium derivatives and their substance P (SP) antagonist activity are described. All compounds were evaluated for their ability to displace SP from neurokinin-1 (NK-1) receptor sites using standard receptor binding methodology (rat forebrain membrane). 1,3-Diethyl-2-[3-(1,3-dihydro- 1,3,3-trimethyl-2H-indol-2-ylidene)-1-propenyl]-1H-naphth[2,3-d]imidazolium chloride (7a), a representative compound in this series, was further evaluated for SP antagonist activity in a guinea pig ileum contractility assay. In vivo SP antagonist activity of 7a was demonstrated using SP-induced salivation and paw edema models performed in rats.

Copper catalyzed photoredox synthesis of alpha-keto esters, quinoxaline, and naphthoquinone: Controlled oxidation of terminal alkynes to glyoxals

Herein, we report a facile visible light induced copper catalyzed controlled oxidation of terminal CC alkynes to alpha-keto esters and quinoxalines via formation of phenylglyoxals as stable intermediates, under mild conditions by using molecular O2 as a sustainable oxidant. The current copper catalysed photoredox method is simple, highly functional group compatible with a broad range of electron rich and electron poor aromatic alkynes as well as aliphatic alcohols (1, 2 and 3 alcohols), providing an efficient route for the preparation of alpha-keto esters (43 examples), quinoxaline and naphthoquinone with higher yields than those in the literature reported thermal processes. Furthermore, the synthetic utility of the products has been demonstrated in the synthesis of two biologically active molecules, an E. coli DHPS inhibitor and CFTR activator, using the current photoredox process. In addition, we applied this methodology to the one-pot synthesis of a heterocyclic compound (quinoxaline, an FLT3 inhibitor) by trapping the intermediate phenylglyoxal with O-phenylenediamine. The intermediate phenylglyoxal can also be isolated and further reacted with an internal alkyne to form naphthoquinone. This process can be readily scaled up to the gram scale.

Aerobic Oxidation of Diverse Primary Alcohols to Carboxylic Acids with a Heterogeneous Pd-Bi-Te/C (PBT/C) Catalyst

Heterogeneous catalytic aerobic oxidation methods represent a near-ideal approach for the conversion of primary alcohols to carboxylic acids. Here, we report that a heterogeneous catalyst composed of Pd, Bi, and Te supported on activated carbon is highly effective for the oxidation of diverse benzylic and aliphatic primary alcohols, including 5-(hydroxymethyl)furfural (HMF) and substrates bearing heterocycles and other important functional groups. In many cases, the desired carboxylic acid product is obtained in >90% yield. Additionally, the catalyst has been demonstrated in a continuous-flow packed-bed reactor for the oxidation of benzyl alcohol, achieving near-quantitative yield while undergoing over 30 000 turnovers.

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.Recommanded Product: Tetrahydrofuran-3-carboxylic acid, you can also check out more blogs about89364-31-8
