We report an efficient and straight forward access to nitrile substituted enol esters via ionic liquid [BMIM]OH mediated hydrocarboxylation of alkynylnitriles under mild conditions. This atom economical transition metal-free protocol gives an easy access to a variety of such enol esters with excellent regio and Z-stereoselectivity. Reusability of [BMIM]OH without losing of significant amount of yield is another noticeable feature of this article.

A series of tetrahydro-ss-carbolines substituted with an alkyl or acyl side chain was synthesized and screened for its antifungal activity against plant pathogenic fungi (Bipolaris oryzae, Curvularia lunata, Fusarium semitectum, and Fusarium fujikuroi). The structure activity relationship revealed that the substituent at the piperidine nitrogen plays an important role for increasing antifungal activities. In this series, 2-octyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole (3g) displayed potent antifungal activities with a minimum inhibitory concentration of 0.1 mu g/mL, including good inhibitory activity to the radial growth of fungus at a concentration of 100 mu g/mL compared to amphotericin B.

The novel coronavirus disease COVID-19 that emerged in 2019 is caused by the virus SARS CoV-2 and named for its close genetic similarity to SARS CoV-1 that caused severe acute respiratory syndrome (SARS) in 2002. Both SARS coronavirus genomes encode two overlapping large polyproteins, which are cleaved at specific sites by a 3C-like cysteine protease (3CL(pro)) in a post-translational processing step that is critical for coronavirus replication. The 3CL(pro) sequences for CoV-1 and CoV-2 viruses are 100% identical in the catalytic domain that carries out protein cleavage. A research effort that focused on the discovery of reversible and irreversible ketone-based inhibitors of SARS CoV-1 3CL(pro) employing ligand-protease structures solved by X-ray crystallography led to the identification of 3 and 4. Preclinical experiments reveal 4 (PF-00835231) as a potent inhibitor of CoV-2 3CL(pro) with suitable pharmaceutical properties to warrant further development as an intravenous treatment for COVID-19.

Predicting the acute toxicity of a large dataset of diverse chemicals against fathead minnows (Pimephales promelas) is challenging. In this paper, 963 organic compounds with acute toxicity towards fathead minnows were split into a training set (482 compounds) and a test set (481 compounds) with an approximate ratio of 1 : 1. Only six molecular descriptors were used to establish the quantitative structure-activity/toxicity relationship (QSAR/QSTR) model for 96 hourpLC(50)through a support vector machine (SVM) along with genetic algorithm. The optimal SVM model (R-2= 0.756) was verified using both internal (leave-one-out cross-validation) and external validations. The validation results (q(int)(2)= 0.699 andq(ext)(2)= 0.744) were satisfactory in predicting acute toxicity in fathead minnows compared with other models reported in the literature, although our SVM model has only six molecular descriptors and a large data set for the test set consisting of 481 compounds.

The dihedral angle between the planar amidic fragment and the haloaryl ring is 62.97 (5)degrees in (I) but 77.72 (12)degrees and 75.50 (5)degrees in (II) and (III), respectively. Despite their similarity in constitution and conformation, the supramolecular interactions in (I)-(III) differ: in (I), a combination of C-H center dot center dot center dot O and C-H center dot center dot center dot pi(arene) hydrogen bonds links the molecules into a three-dimensional framework structure, but there are no hydrogen bonds of any sort in either (II) or (III), although the structure of (III) contains a short Cl center dot center dot center dot Cl contact between inversion-related pairs of molecules.

Text. A general method for the synthesis of structural diversity and complexity of azepines from aldimine esters and beta ‘-acetoxy allenoates is reported. Under phosphine catalysis, a [4+3] cycloaddition for the formation of 1,3-dihydro-2H-azepine-2,2,4-tricarboxylates was achieved with broad substrate scope under mild reactions. A switchable process was given and a variety of important 2,3-dihydrochromeno[4,3-b]azepin-6(1H)-ones were selectively formed when the reaction was performed in the presence of Cs2CO3 and PPh3, which involved an intramolecular ester group migration and subsequent lactonization of 1,3-dihydro-2H-azepine-2,2,4-tricarboxylates. Besides easy handle process, high synthetic value of resulting products, it is worth to note that this work showed the novel example of 1,5-ethoxycarbonyl migration.

An efficient method for the directing group controlled rhodium-catalyzed addition reaction of oxa/azabicylic alkenes with aromatic ketones and benzoic acids has been developed. The ketones and benzoic acids afforded different addition products when reacted with oxa/azabicyclic alkenes. The reaction between ketones and azabenzonorbornadienes furnished the ring-opening addition products. The reaction between benzoic acids and aza/oxabicyclic alkenes proceeded in the absence of silver salt, giving the 1:2 hydroarylation products in yields up to 96%.

A collection of N-substituted quinolin-2(1H)-ones were screened against a panel of clinically relevant protozoa (Leishmania, Trypanosoma and Acanthamoeba). Three quinolin-2(1H)-one compounds were identified as selective anti-Acanthamoeba agents. Further assessment revealed that these compounds were active against both trophozoite and cyst forms of A. castellanii Neff, and caused protozoa death via apoptosis. The data presented herein identify N-acyl quinolin-2(1H)-ones as a promising new class of selective anti-Acanthamoeba agents.

Unprecedented triazinyl-isoxazoles were afforded via an effective cycloaddition reaction between nitrile oxides and the scarcely described 2-ethynyl-4,6-dimethoxy-1,3,5-triazine as dipolarophile. The biological evaluation of the newly synthesized compounds showed that the inhibition of human farnesyltransferase by zinc complexation could be improved with triazine-isoxazole moieties. The replacement of the isoxazole unit by a pyrrolidin-2-one was detrimental to the inhibitory activity while the pyrrolidin-2-thione derivatives conserved the biological potential. The potential of selected compounds to disrupt protein farnesylation in Chinese hamster ovary (CHO) cells transfected with pEGFP-CAAX was also evaluated.
