Reactivity of p-phenyl substituted beta-enamino compounds using k- 10/ultrasound. II [1]. Synthesis of isoxazoles and 5-isoxazolones

The condensation of 4-phenyl substituted beta-enamino ketones 1a-d and beta- enamino esters 5a-d with hydroxylamine hydrochloride using K-10 as the solid support under sonication was studied to evaluate the formation of isoxazole and 5-isoxazolone rings from beta-enamino compounds with a substituted aromatic ring. Isoxazoles 2a-c, 3c-d and 5-isoxazolones 6a-c and 7a-d were obtained. The use of K-10/ultrasound in this reaction furnished novel results in some cases.

An enantioselective fluorimetric assay for alcohol dehydrogenases using albumin-catalyzed beta-elimination of umbelliferone

3-hydroxybutyl umbelliferyl ethers (R)-1 and (S)-1 are fluorogenic substrates for alcohol dehydrogenases. Their oxidation forms ketone 2, which undergoes beta-elimination of umbelliferone under catalysis by bovine serum albumin, leading to a >20-fold fluorescence increase at lambda(em) = 460 ¡À 20 nm (lambda(ex) = 360 ¡À 20 nm). Enantioselectivity is determined in two separate tests with each enantiomeric substrate.

Recent advances in utilities of active iodine reagents as organo-catalysts in organic synthesis

Since 1990s, the application of organo-iodine reagents as oxidant in organic synthesis went through explosive progress. In early times, most of organo-iodine reagents were used as stoichiometric terminal or co-oxidants in oxidative reactions, which inevitably led a lower atom coefficient of utilization and environmental issues. In this regard, it is very urgent to develop varies of efficient approaches of the catalytic utilization of organo-iodine reagents in organic synthesis. Recently, more and more iodine compounds were used as organo-catalysts for many kinds of reactions, which were revolutionary progress for iodine chemistry, and could also meet the need of green chemistry. In this review, we presented an overview of catalytic utilization of active iodine reagents as organo-catalysts in organic synthesis and also some successful examples for asymmetric catalysis. We focused on the recent synthetic strategies, applications of organo-iodine reagents and its mechanism as organo-catalysts, and finally gave a perspective of future development.

Direct synthesis of 4-fluoroisoxazoles through gold-catalyzed cascade cyclization-fluorination of 2-alkynone O-methyl oximes

A tandem protocol for the synthesis of fluorinated isoxazoles has been developed via catalytic intramolecular cyclizations of 2-alkynone O-methyl oximes and ensuing fluorination. The reactions proceed smoothly at room temperature in the presence of 5 mol % of (IPr)AuCl, 5 mol % of AgOTs, 2.5 equiv of Selectfluor, and 2 equiv of NaHCO3. This process features an efficient one-pot cascade route to fluoroisoxazoles with high yields and high selectivity under mild reaction conditions.

Use of Bromine and Bromo-Organic Compounds in Organic Synthesis

Bromination is one of the most important transformations in organic synthesis and can be carried out using bromine and many other bromo compounds. Use of molecular bromine in organic synthesis is well-known. However, due to the hazardous nature of bromine, enormous growth has been witnessed in the past several decades for the development of solid bromine carriers. This review outlines the use of bromine and different bromo-organic compounds in organic synthesis. The applications of bromine, a total of 107 bromo-organic compounds, 11 other brominating agents, and a few natural bromine sources were incorporated. The scope of these reagents for various organic transformations such as bromination, cohalogenation, oxidation, cyclization, ring-opening reactions, substitution, rearrangement, hydrolysis, catalysis, etc. has been described briefly to highlight important aspects of the bromo-organic compounds in organic synthesis.

Novel synthesis of 3,4-diarylisoxazole analogues of valdecoxib: Reversal cyclooxygenase-2 selectivity by sulfonamide group removal

3,4-Diarylisoxazole analogues of valdecoxib [4-(5-methyl-3-phenylisoxazol- 4-yl)-benzensulfonamide], a selective cyclooxygenase-2 (COX-2) inhibitor, were synthesized by 1,3-dipolar cycloaddition of arylnitrile oxides to the enolate ion of phenylacetone regioselectively prepared in situ with lithium diisopropylamide at 0 C. The corresponding 3-aryl-5-methyl-4-phenyl- isoxazoles were easily generated by a dehydration/aromatization reaction under basic conditions of 3-aryl-5-hydroxy-5-methyl-4-phenyl-2-isoxazolines and further transformed into their benzenesulfonamide derivatives. The biochemical COX-1/COX-2 selectivity was evaluated in vitro by using the human whole blood assays of COX isozyme activity. Three compounds not bearing the sulfonamide group present in valdecoxib were selective COX-1 inhibitors.
