A synthesis strategy for the production of a key synthetic intermediate of gulmirecin A was described. The key reaction in the preparation of the 12-membered macrolactone is the Ni(0)-mediated reductive cyclization reaction of ynal using an N-heterocyclic carbene ligand and silane reductant. In addition, the alpha-selective glycosylation reaction of the macrolactone was performed to demonstrate the synthesis of gulmirecin and disciformycin precursors.

We have developed a versatile visible-light-driven cyanoalkylation of quinoxalinones under mild conditions. First, the cyanoalkyl radicals are generated from readily available cyclobutanone oxime esters under blue light irradiation. Then the generated radicals react with heterocycles such as quinoxalinones to give the final cyanoalkylation products. The protocol tolerates a wide range of functional groups. Our cyanoalkylation protocol does not need cyanide-based reagents and also does not need external oxidants. (C) 2019 Elsevier Ltd. All rights reserved.

We report a new application of N-amino-7-azaindole as a new bidentate-directing group for [Ru(p-cymene)Cl-2](2)-catalyzed C(sp(2))-H alkenylation/annulation of N-(1H-pyrrolo[2,3-b]pyridin-1-yl)benzamides with internal alkynes to afford N-isoquinolono-7-azaindole via the formation of C-C and C-N bonds. The reaction shows a wide range of substrate scope with different symmetrical and unsymmetrical alkynes, affording the desired product in good to excellent yields. In the case of unsymmetrical alkynes, a highly regioselective product was obtained, which was confirmed by single-crystal X-ray crystallography. A new ruthenium-4-methyl-N-(1H-pyrrolo[2,3-b]pyridin-1-yl)benzamide complex was isolated, and its structure was confirmed by single-crystal X-ray crystallography.

The development of sub-nanometric metal particles (<1 nm) as advanced heterogeneous catalysts has received considerable interest due to their outstanding catalytic performance, while the synthesis and stabilization of sub-nanometric catalysts (SNCs) without using additional surface capping agents remains a challenge. Herein, we report the synthesis of novel three-dimensional pyrenyl graphdiyne (Pyr-GDY) ultrafine nanofibers (3-10 nm), which can serve as an ideal substrate for electroless deposition and stabilization of Pd SNCs through the terminal uncoupled acetenyl groups in Pyr-GDY, with an average Pd particle size of only 0.83 nm. The as-synthesized Pd/Pyr-GDY composite shows extremely high catalytic activities for the reduction of nitroarenes to arylamines and Suzuki coupling reactions, 300 and 25 times higher than those of commercial Pd/C, respectively. The outstanding catalytic performance can be ascribed to the sub-nanometric Pd particles with a clean surface, and the unique three-dimensional network structure of Pyr-GDY, being favorable for rapid mass transfer. Our result provides an ideal carbon material for electroless deposition and stabilization of other SNCs with a clean surface, which will display outstanding catalytic activity for various catalytic reactions.

Regioselectivity of Ln(OTf)(3)-catalysed alcoholysis of 2,3- and 3,4-epoxy alcohols was closely investigated to expand the scope of the transformations. The synthetic use was demonstrated by application to the construction of 4-propoxy-5-hydroxy-2,3-pentanedione (C4-propoxy-HPD), which is a potent synthetic mediator in AI-2 quorum sensing.

Calcium dependent protein kinase 1 (CDPK1) is an essential Ser/Thr kinase that controls invasion and egress by the protozoan parasite Toxoplasma gondii. The Gly gatekeeper of CDPK1 makes it exquisitely sensitive to inhibition by small molecule 1H-pyrazolo[3,4-d]pyrimidine-4-amine (PP) compounds that are bulky ATP mimetics. Here we rationally designed, synthesized, and tested a series of novel PP analogs that were evaluated for inhibition of CDPK1 enzyme activity in vitro and parasite growth in cell culture. Optimal substitution on the PP scaffold included 2-pyridyl ethers directed into the hydrophobic pocket and small carbocyclic rings accessing the ribose-binding pocket. Further optimization of the series led to identification of the lead compound 3a that displayed excellent potency, selectivity, safety profile, and efficacy in vivo. The results of these studies provide a foundation for further work to optimize CDPK1 inhibitors for the treatment of acute and chronic toxoplasmosis.

The oxidative coupling of carboxylic acids with liquid ketones and cyclic ethers has been accomplished in minutes using t-butyl hydroperoxide in the presence of tetrabutylammonium iodide under microwave irradiation in the absence of a solvent. In addition to drastically shortening the reaction times, the use of microwaves resulted, in general, in yields equal to or higher than those obtained by conventional heating.

A three-component reaction between benzyne, oxazolines and chloroform was developed for the synthesis of trichloromethylated chiral oxazolidines. Benzyne not only serves as an electrophile towards oxazolines but also acts as a base for the deprotonation of chloroform. The dual functions of benzyne enable the trichloromethylation of chiral oxazolines and thus construct chiral N, Oquaternary stereocenters.

beta-Glucuronidase is responsible for the catalytic deconjugation of beta-D-glucuronides. beta-Glucuronidase has evolved to be a viable molecular target for numerous therapeutic treatments. It plays a pivotal role in the metabolism of drugs and endogenous substances. Herein, we report the inhibitory potentials of newly developed and modular benzimidazole-triazolothiadiazole hybrids spaced through a phenyl linker (1-26) and their interactions with the beta-glucuronidase. All analogues showed IC50 values in the range of 1.30 +/- 0.10 to 44.10 +/- 0.80 mu M, and hence were found to have outstanding inhibitory potential as compare to the standard D-saccharic acid 1,4-lactone (IC50 = 48.4 +/- 1.25 mu M). These modular hybrids were successfully synthesized, rigorously characterized through various spectroscopic techniques. Molecular docking studies further revealed the potential interactions between the inhibitor and active amino acid site in beta-glucuronidase. These findings helped in identifying the potential for new drug candidates. A Plausible structure activity relationship (SAR) were established which suggested that variation in the inhibitory potential was mainly based upon the substituents attached to the phenyl ring.

Activation of carbonyl moiety is one of the most rudimentary approaches in organic synthesis and is crucial for a plethora of industrial-scale condensation reactions. In esterification and aldol condensation, which represent two of the most important reactions, the susceptibility of the carbonyl group to nucleophile attack allows the construction of a variety of useful organic compounds. In this context, there is a constant need for development of and improvement in the methods for addition-elimination reactions via activation of carbonyl functionality. In this paper, an advanced methodology for the direct esterification of carboxylic acids and alcohols, and for aldol condensation of aldehydes using widely available, inexpensive, and metal-free 1,3-dibromo-5,5-dimethylhydantoin under neat reaction conditions is reported. The method is air- and moisture-tolerant, allowing simple synthetic and isolation procedures for both reactions presented in this paper. The reaction pathway for esterification is proposed and a scale-up of certain industrially important derivatives is performed.
