Synthesis of 6-amino-5-cyano-1,4-disubstituted-2(1h)-pyrimidinones via copper-(i)-catalyzed alkyne-azide ‘click chemistry’ and their reactivity

In this paper we present the room temperature synthesis of a novel serie of 1,4-disubstituted-1,2,3-triazoles 4a-l by employing the (3 + 2) cycloaddition reaction of pyrimidinones containing alkyne functions with different model azides in the presence of copper sulphate and sodium ascorbate. To obtain the final triazoles, we also synthesized the major precursors 6-amino-5-cyano-1,4- disubstituted-2(1H)-pyrimidinones 3a-r from ethyl 2,2-dicyanovinylcarbamate derivatives 2a-c and various primary aromatic amines containing an alkyne group. The triazoles were prepared in good to very good yields.

Synthesis and biological evaluation of direct thrombin inhibitors bearing 4-(piperidin-1-yl)pyridine at the P1 position with potent anticoagulant activity

The design and synthesis of a new class of nonpeptide direct thrombin inhibitors, built on the structure of 1-(pyridin-4-yl)piperidine-4-carboxamide, are described. Starting from a strongly basic 1-amidinopiperidine derivative (6) showing poor thrombin (fIIa) and factor Xa (fXa) inhibition activities, anti-fIIa activity and artificial membrane permeability were considerably improved by optimizing the basic P1 and the X-substituted phenyl P4 binding moieties. Structure-activity relationship studies, usefully complemented with molecular modeling results, led us to identify compound 13b, which showed excellent fIIa inhibition (Ki = 6 nM), weak anti-Xa activity (K i = 5.64 muM), and remarkable selectivity over other serine proteases (e.g., trypsin). Compound 13b showed in vitro anticoagulant activity in the low micromolar range and significant membrane permeability. In mice (ex vivo), 13b demonstrated anticoagulant effects at 2 h after oral dosing (100 mg¡¤kg-1), with a significant 43% prolongation of the activated partial thromboplastin time (aPTT), over controls (P < 0.05). 214894-89-0, Interested yet?

A new umpolung for direct gamma-regioselective nucleophilic addition of alcohols to gamma-enolizable alpha,beta-unsaturated aldehydes

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.

Gold-Catalyzed Post-Ugi Cascade Transformation for the Synthesis of 2-Pyridones

A gold-catalyzed post-Ugi cascade transformation for the synthesis of 2-pyridones is described. The process involves furan?alkyne cyclization followed by furan ring-opening and cleavage of the isocyanide-originated fragment. The initially formed cis double bond can isomerize into a more stable trans double bond upon prolonged exposure to a strong Br¡ãnsted acid. Thus, the overall strategy provides a viable access towards two types of 2-pyridones.

Synthesis and evaluation of 2-(arylamino)imidazoles as alpha2-adrenergic agonists

A series of 2-(arylamino)imidazoles was synthesized and evaluated for activity at alpha1- and alpha2-adrenoceptors. This class of agents has been shown to have potent and selective agonist activity at the alpha2-adrenoceptors. The most potent member of this class, 2-[(5-methyl-1,4-benzodioxan-6- yl)amino]imidazole, proved efficacious for the reduction of intraocular pressure upon topical administration and for the reduction of blood pressure upon intravenous administration. During the course of our studies, we developed a new reagent that allowed rapid assembly of the target compounds. This reagent, N-(2,2-diethoxyethyl)carbodiimide, was convenient to prepare and was stable under low-temperature storage conditions.

Rhodium(I)-catalyzed regiospecific dimerization of aromatic acids: Two direct C-H bond activations in water

2,2′-Diaryl acids are key building blocks for some of the most important and high-performance polymers such as polyesters and polyamides (imides), as well as structural motifs of MOFs (metal-organic frameworks) and biological compounds. In this study, a direct, regiospecific and practical dimerization of simple aromatic acids to generate 2,2′-diaryl acids has been discovered, which proceeds through two rhodium-catalyzed C-H activations in water. This reaction can be easily scaled up to gram level by using only 0.4-0.6 mol% of the rhodium catalyst. As a proof-of-concept, the natural product ellagic acid was synthesized in two steps by this method. On the double: An efficient, regiospecific, and general oxidative dimerization of simple aryl acids to generate diaryl acids was developed. The reaction involves two direct aryl C-H activations catalyzed by rhodium, uses water as the solvent, and can be easily scaled up. The natural product ellagic acid was obtained in only two steps by using this method.

Optimization of a Series of Mu Opioid Receptor (MOR) Agonists with High G Protein Signaling Bias

While mu opioid receptor (MOR) agonists are especially effective as broad-spectrum pain relievers, it has been exceptionally difficult to achieve a clear separation of analgesia from many problematic side effects. Recently, many groups have sought MOR agonists that induce minimal betaarrestin-mediated signaling because MOR agonist-treated betaarrestin2 knockout mice were found to display enhanced antinociceptive effects with significantly less respiratory depression and tachyphylaxis. Substantial data now exists to support the premise that G protein signaling biased MOR agonists can be effective analgesic agents. We recently showed that, within a chemical series, the degree of bias correlates linearly with the magnitude of the respiratory safety index. Herein we describe the synthesis and optimization of piperidine benzimidazolone MOR agonists that together display a wide range of bias (G/betaarr2). We identify structural features affecting potency and maximizing bias and show that many compounds have desirable properties, such as long half-lives and high brain penetration.
