An unprecedented example of a NHC-catalyzed acylation reaction promoted by an oxidant CCl3CN is described. This protocol features several advantages, including mild reaction conditions, broad substrate scope, and easy operation. In addition, low cost, low boiling point, and small molecular weight allow CCl3CN to be an attractive and amenable oxidant. Meanwhile, this formal dehydrogenative coupling reaction of aldehydes and alcohols involves a hydride transfer process.

Efficient access to diverse screening compounds with desirable, lead-like properties can be a bottleneck in early drug discovery and chemical biology. Herein we present an efficient, rapid route to three structurally distinct classes of compounds (A-C) from a single precursor, which in turn is available through a one-pot Petasis 3-component reaction/Diels-Alder cascade reaction. We demonstrate the versatility of the approach through the synthesis of 35 exemplary compounds from the three classes, as well as by the production of 2188 final compounds, which have been included in the Joint European Compound Library of the European Lead Factory.

A surfactant based oxodiperoxo molybdenum complex, which could activate molecular oxygen, has been employed as a catalyst for controlled oxidation of benzylic alcohols to corresponding carbonyls. The oxidation reactions were carried out under aqueous environment, however, in the absence of any extraneous base or co-catalyst. Sensitive/oxidizable functional groups like cyano, sulfide, hydroxyl, aryl-hydroxyl, alkene (internal/terminal), alkyne (internal/terminal), and acetal were tolerated during the transformations. Such selectivity is attributed to the mild nature of the catalyst. The methodology could also be scaled-up for multi-gram synthesis and the protocol is likely to find practical use since it requires an inexpensive recyclable-catalyst and easily available oxidant (under green conditions). A plausible mechanism is proposed with the help of preliminary computational study. (C) 2019 Elsevier Inc. All rights reserved.

The histamine 3 receptor (H3R) is a presynaptic receptor, which modulates several neurotransmitters including histamine and various essential physiological processes, such as feeding, arousal, cognition, and pain. The H3R is considered as a drug target for the treatment of several central nervous system disorders. We have synthesized and identified a novel series of 4-aryl-6-methyl-5,6,7,8-tetrahydroquinazolinamines that act as selective H3R antagonists. Among all the synthesized compounds, in vitro and docking studies suggested that the 4-methoxy-phenyl-substituted tetrahydroquinazolinamine compound 4c has potent and selective H3R antagonist activity (IC50 < 0.04 mu M). Compound 4c did not exhibit any activity on the hERG ion channel and pan-assay interference compounds liability. Pharmacokinetic studies showed that 4c crosses the blood brain barrier, and in vivo studies demonstrated that 4c induces anorexia and weight loss in obese, but not in lean mice. These data reveal the therapeutic potential of 4c as an anti-obesity candidate drug via antagonizing the H3R. Recommanded Product: 3-Pyridinecarboxaldehyde.

A new three-component strategy from aldehyde, p-toluenesulfonyl hydrazide and potassium thiocyanate for the synthesis of 2-aminothiadiazoles promoted by I-2 under metal-free conditions has been described. Potassium thiocyanate was used as an odorless and low-toxicity sulfur source. A wide range of aromatic aldehydes can smoothly undergo the three-component cyclization reaction under the optimized conditions to give the corresponding products in moderate to good yields.

Candida albicans biofilm represents a major clinical problem due to its intrinsic tolerance to anti-fungal compounds and it has been highly related to infections in catheterized patients. Few compounds are described as able to inhibit biofilm formation or to interfere with preformed biofilm of C. albicans. Here we report the in vitro evaluation of anti-biofilm activity on C albicans ATCC 10231 of a series of new and already known amine and amide indole derivatives. Among the studied compounds, fifteen resulted active on C albicans ATCC 10231 biofilm, with BMIC50 <= 16 mu g/mL. Three of them (7, 23 and 33) showed a selectivity towards mature biofilm and the most active of them was the compound 23 (BMIC50 = 4 mu g/mL). On the other hands, two different compounds (21 and 22) were selective towards biofilm formation with BMIC50 values of 8 mu g/mL Otherwise, compounds 16 and 17 resulted active on biofilm formation, with BMIC50 of 8 mu g/mL and 2 mu g/mL respectively, and on mature biofilm with BMIC50 of 2 mu g/mL. These two last compounds also showed an interesting activity towards the planktonic cells of C albicans. A selection of the more active compounds was also evaluated on different C albicans strains (PMC1042, PMC1083 and ATCC 10261), showing a comparable or higher anti-biofilm activity, especially on mature biofilm. In vivo toxicity studies using the Galleria mellonella larvae, were finally carried out on more active indole derivatives, showing that they are poorly toxic even at the highest concentrations tested (500-1000 mu g/mL).

A new strategy to 2-aminochromanes through catalyst-free cascade reaction of 3-trifluoroacetyl-4H-chromenes and 4H-chromene-3-carbaldehydes with cyclic secondary amines is presented. The reaction proceeds through subsequent 1,4- and 1,2-additions of amine, bimolecular elimination of trifluoroacetamide or formamide, and 6-exotrig cyclization. The latter stage is a very rare example of addition of phenols to enamines. The obtained semicyclic N,O-acetals were applied as useful precursors for the synthesis of other chromanes.

2-Aminoimidazoles represent useful synthons for incorporation into medicinal compounds. They provide hydrogen bonding loci, water solubilizing properties and convenient handles for further synthetic elaboration. The rapid and facile generation of diverse 2-aminoimidazoles via tandem addition cyclization reaction of vinyl azides and cyanamide has been investigated. These reactions proceeded through either thermal or photochemical activation of vinyl azides and demonstrated wide substrate scope. In the photochemical reaction, blue light (456 nm) alone triggered photolysis of the azide without the addition of a photocatalyst. Possible reaction mechanisms in the context of substrate reactivity are discussed.
