A mild and efficient route for the synthesis of conjugated trienes via nitroethane-mediated ring contraction of 2-oxobenzo[h]chromenes/2H-pyran-2-ones followed by decarboxylative rearrangement of the obtained spirobutenolides and butenolides is described. The (E)-isomer of trienes was obtained by step-wise and one-pot approaches from 2-oxobenzo[h]chromenes. Butenolides 4a-l as new substrates have been developed for the construction of trienes. The mixture of the (E)- and (Z)-isomers of spirobutenolides undergoes decarboxylative rearrangement in the presence of sodium ethoxide as a base to yield the (E)-isomer of trienes, while the (E)-isomer of butenolides reacts to give a mixture of (2E,4E)- and (2E,4Z)-isomers of trienes in an almost steady ratio of 45 : 55 or 1 : 1.2. The structure and geometry of the obtained butenolides and trienes were confirmed by single-crystal X-ray analysis.

In the present study, the partly and fully-substituted monospiro (4-6, 4a-6d), cis-dispiro (7-9), trans-dispiro (10-15) cyclotriphosphazenes were synthesized for the investigations of their chemical, stereogenic and biological properties. The cis/trans phosphazenes (7-12) have two stereogenic P centers. They are expected to be in meso and racemic forms. In addition, the structures of four compounds were evaluated using X-ray crystal-lographic data. Compound 13 was found to be a single enantiomer (RR) in the solid state, as also proved with its CD spectrum. The antibacterial and antifungal activities of the phosphazenes were elucidated for against Gram-positive (G+) and Gram-negative (G-) bacteria, and yeast strains, respectively. Of the compounds, 14 exhibits strong antimicrobial activity against most of the tested organisms, especially B. cereus and E. hirae. MBC and MFC values of compounds on different bacterial and fungal species ranged from < 9.8 mu M to 2500 mu M. Furthermore, the cytotoxic activities of 6, 4c, 10 and 14 were investigated against L929 fibroblast and DLD-1 cells, and 14 was the most cytotoxic compound against DLD-1.

The catalytic enantioselective synthesis of a-chiral olefins represents a valuable strategy for rapid generation of structural diversity in divergent syntheses of complex targets. Herein, we report a protocol for the dual CuH- and Pd-catalyzed asymmetric Markovnikov hydroalkenylation of vinyl arenes and the anti-Markovnikov hydroalkenylation of unactivated olefins, in which readily available enol triflates can be utilized as alkenyl coupling partners. This method allowed for the synthesis of diverse alpha-chiral olefins, including tri- and tetrasubstituted olefin products, which are challenging to prepare by existing approaches.

A simple and efficient Fe-catalyzed regioselective alkylation of 1,4-quinones and coumarins, using functionalized alkyl bromides as alkylating reagents, has been developed. The reaction proceeds under mild conditions with the addition of alkyl bromides to a wide range of 1,4-quinone and coumarin derivatives with a broad substrate scope and wide functional group tolerance to provide the products in good yields. Further application of these strategies could be extended to important biologically active antimalarial lead drugs, such as plasmodione on a gram scale in a single step for medicinal purposes.

The cascade amination/cyclization ofN-arylacrylamides with alkyl amines under visible-light photoredox catalysis is realized via intermediacy of aminium radicals. The aminium radicals are generated by a two-step sequence which involves N-chlorination of alkyl amines and subsequent reductive N-Cl cleavage. This method provides a convenient access to aminated oxindoles.

Currently available drugs being used to treat leishmaniasis have several shortcomings, including high toxicity, drug administration that requires hospitalization, and the emergence of parasite resistance against clinically used drugs. As a result, there is a dire need for the development of new antileishmanial drugs that are safe, affordable, and efficient. In this study, two new series of synthesized quinazolinone derivatives were investigated as potential future antileishmanial agents, by assessing their activities against theLeishmania(L.)donovaniandL. majorspecies. The cytotoxicity profiles of these derivatives were assessed in vitro on Vero cells. The compounds were found to be safer and without any toxic activities against mammalian cells, compared to the reference drug, halofuginone, a clinical derivative of febrifugine. However, they had demonstrated poor antileishmanial growth inhibition efficacies. The two compounds that had been found the most active were the mono quinazolinone2dand the bisquinazolinone5bwith growth inhibitory efficacies of 35% and 29% for theL. majorandL. donovani9515 promastigotes, respectively. These outcomes had suggested structural redesign,inter aliathe inclusion of polar groups on the quinazolinone ring, to potentially generate novel quinazolinone derivatives, endowed with effective antileishmanial potential.

The Cl exchange reaction of hexachlorocyclotriphosphazene, N3P3Cl6 (1), with one equimolar amount of sodium salt of N/O donor type bidentate ligand containing a 2-pyridyl pendant arm (2) afforded, regioselectively, the partly substituted 2-pyridyl(N/O)spirocyclotriphosphazene (3; with a yield of 65%) in THF. The reactions of 3 with excess pyrrolidine, morpholine and 1,4-dioxa-8-azaspiro[4,5]decane (DASD) led to the formation of the tetraamino-2-pyridyl(N/O)spirocyclotriphosphazenes (3a-3c) in high yields. Compound 3 also gave both tetrapiperidino (3d) and gem-bispiperidino (3e) products with excess piperidine. The structures of all the compounds were determined by elemental analyses, ESI-MS, FTIR, HSQC, HMBC and H-1, C-13, and P-31 NMR techniques. The crystal structure of 3c was identified by single crystal X-ray crystallography. Besides, the compound 3e had one stereogenic P atom, and its chirality was verified by P-31 NMR spectroscopy in the presence of (S)-(+)-2,2,2-trifluoro-1-(9′-anthryl)-ethanol (CSA).

A practical and scalable electrochemical oxidation of S-H and N-H was developed. This oxidant-and catalyst-free electrochemical process enables S-N bond formation with inexpensive nickel electrodes in an undivided cell. This procedure exhibits broad substrate scopes and good functional-group compatibility. A 50 g scale oxidative coupling augurs well for industrial applications.

Metal-catalyzed beta-C-H functionalization of saturated carbonyls via dehydrogenative desaturation proved to be a powerful tool for simplifying synthesis of valuable beta-substituted carbonyls. Here, we report a copper-catalyzed dehydrogenative gamma-C(sp(3))-H amination of saturated ketones that initiates the three-component coupling of saturated ketones, amines and N-substituted maleimides to construct polysubstituted anilines. The protocol presented herein enables both linear and alpha-branched butanones to couple a wide spectrum of amines and various N-substituted maleimides to produce diverse tetra- or penta-substituted anilines in fair-to-excellent yields with good functional group tolerance. The mechanism studies support that this ketone dehydrogenative gamma-C(sp(3))-H amination was triggered by the ketone alpha,beta-dehydrogenation desaturation that activates the adjacent gamma-C(sp(3))-H bond towards functionalization. This alpha,beta-dehydrogenation desaturation-triggered cascade sequence opens up a new avenue to the remote C(sp(3))-H functionalization of saturated ketones and has the potential to enable the rapid syntheses of complex compounds from simple starting materials.

Novel fluorinated 2-substituted 1,3-benzothiazin-4-ones were obtained through the addition of N-nucleophiles to ortho-fluorobenzoylisothiocyanates, followed by cyclization of fluorobenzoyl-thioureas. Synthetic approaches to original 2-cycloalkylimino- and 2-carbonylpiperazino- substituted benzothiazinones, bearing different number of fluorine atoms in the benzene ring have been found. 2-Ethoxycarbonylpiperazino-5-fluoro-1,3-benzothiazin-4-one proved to exhibit a high tuberculostatic activity in vitro (MIC 0.7 microgram/mL), thus indicating that a search of biologically active compounds in this family of heterocycles appears to be a reasonable approach.
