A number of novel sulfonamide derivatives of 5-substituted-3- methylisoxazole were synthesized and characterized, starting from 3,5-dimethylisoxazole. Key steps include the generation of 3,5- dimethylisoxazole-4-sulfonamides followed by their reactions with N-(dimethoxymethyl)-N,N-dimethylamine or various aromatic and heteroaromatic aldehydes. As a result, a series of novel aryl/heteroaryl- and aminovinylsubstituted derivatives of the isoxazole heterocycle were obtained. The scope and limitations of the developed approach are discussed.

Synthetic Route of 2879-20-1, Chemical Research Letters, May 2021. The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis. 2879-20-1, Name is 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone,introducing its new discovery.

To obtain further insight into the new ruthenium-catalyzed reaction of carbon-hydrogen bonds in aromatic ketones with olefins, the effect of various substituents at the aromatic ring is examined. Reaction of o-methylacetophenone with triethoxyvinylsilane (2) in the presence of [Ru(H)2(CO)(PPh3)3] (3)as the catalyst gave the 1 : 1 addition product in quantitative yield. Similarly, the ketone having an o-CF3 group gave the coupling product 9 in 92% yield. However, ortho substituents such as OMe, F, and CN, seem to react with and kill the catalyst so that no efficient reaction was attained. In the cases of the reactions of p-methoxy- and p-fluoroacetophenones with 2, the corresponding 1 : 2 addition products were obtained as the major product. In the cases of m-substituted acetophenones, two different C-H bonds at the ortho positions are available. The C-C bond formation preferentially occurred at the sterically less congested positions. Exceptions are the reactions of m-methoxy- and m-fluoroacetophenones, in which the C-C bond formation took place preferentially at the more congested position. This may be due to the coordination of oxygen or fluorine atom to ruthenium. The factors controlling these selectivities are discussed.

An efficient copper-TEMPO-catalyzed one-pot synthesis of alpha-ketoamides from phenethyl alcohol derivatives was developed firstly. Moreover, molecular oxygen in open air was employed as the oxidant with a broad substrate scope, which makes this methodology more practical. Based on some control experiments, a plausible mechanism was proposed.

Thermochemical conversion processes such as supercritical fluid extraction are used for producing biofuels from biomass. Supercritical fluid extraction process is decomposition process of lignocellulose or other organic materials thermally under supercritical conditions at 250-400 C temperature range under high pressure (4-5 MPa). In this study, the supercritical fluid extraction was used to produce bio-oils from algae. Supercritical fluid extraction trials were performed in a cylindrical reactor (75 mL) in organic solvents (acetone, ethanol and isopropanol) under supercritical conditions with (ferric chloride, potassium hydroxide) and without catalyst at the temperatures of 255, 275 and 295 C. The effects of process variables including temperature and catalyst on product yields were investigated. The produced liquids at 295 C in supercritical liquefaction were analyzed and characterized by elemental, GC-MS and FT-IR. 160, 122 and 108 different types of compounds were identified by GC-MS obtained in acetone, ethanol and isopropanol respectively. Bio-oils from supercritical liquefaction were composed of various organics including aromatics, nitrogenated and oxygenated compounds. Bio-oils obtained from supercritical liquefaction were found to have higher calorific values and superior fuel properties compared to feedstock.
