This report describes a carboxylate-assisted palladium-catalysed Catellani reaction, which is compatible with ortho-amination and unactivated C(sp(2))-H arylation. This method was used to synthesize a series of 1-amino substituted dihydrophenanthridines, phenanthridines and 6H-benzo[c]chromenes. Based on kinetic isotope experiments, the kinetic curve proves that pivalic acid accelerates the reaction rate of unactivated C(sp(2))-H activation, and thus this rate can keep up with the five membered aryl-norbornene-palladacycle (ANP) intermediate.

N-Boc deprotection (deBoc) is a common reaction in pharmaceutical research and development, as well as pharma manufacturing. Use of a catalyst lowers the required reaction temperature, and heterogeneous catalysts allow the reaction to be conducted in a continuous flow reactor with a low-boiling solvent, facilitating product separation and enhancing efficiency and productivity relative to a batch process. In this study, we explore the use of simple solid Bronsted acid catalysts to achieve continuous N-Boc deprotection of amines, without additional workup steps. Using THF as the solvent, H-BEA zeolite affords high yields of a variety of aromatic and aliphatic amines, often in residence times of less than a minute at 140 degrees C. The same catalyst/solvent combination is ineffective in batch conditions, due to the much lower temperature of refluxing THF. Boc-protected p-chloroaniline was deprotected with a throughput of 18 mmol p-chloroaniline per h per g(cat), sustained over 9 h. The active sites of the zeolite do not appear to be directly associated with the Al framework substitution in the micropores, since partially ion-exchanged Na/H-BEA shows activity similar to H-BEA. The strong Bronsted acid sites (framework [Si(OH)Al]), are likely poisoned by the amine product. Moderate Bronsted acid sites associated with silanol defects near Al on or near the external surface (and not susceptible to Na+-exchange) are presumably the active sites, since they are not poisoned even by more basic aliphatic amines.

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.

Metal-catalyzed cross-coupling reactions are among the most important transformations in organic synthesis. However, the use of C-H activation for sp(2) C-N bond formation remains one of the major challenges in the field of cross-coupling chemistry. Described herein is the first example of the synergistic combination of copper catalysis and electrocatalysis for aryl C-H amination under mild reaction conditions in an atom-and step-economical manner with the liberation of H-2 as the sole and benign byproduct.

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 formation of nitrile oxides with diazocarbonyl compounds by nitrosyl transfer from tert-butyl nitrite under mild conditions and without the use of a catalyst or an additive is reported. This transformation is broadly applicable to the synthesis of furoxans by dimerization and isoxazoles and isoxazolines by cycloaddition. This methodology is also applied for the millimole-scale synthesis of two biologically active compounds. The formation of the nitrile oxide from a diazoacetamide is stable and confirmed experimentally.

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.
