NOVEL PHENYLSULFONYL OXAZOLE DERIVATIVE AND USE THEREOF

The present invention relates to a novel phenylsulfonyl oxazole derivative and a use thereof and specifically, to a compound represented by Chemical Formula 1 in the present specification or a pharmaceutically acceptable salt thereof, and to a use thereof for prevention, treatment, or improvement of neurodegenerative disease.

A 'sulfonyl-azide-free' (SAFE) aqueous-phase diazo transfer reaction for parallel and diversity-oriented synthesis

Diazo transfer reactions are notoriously associated with the use of potentially explosive sulfonyl azides. The first 'sulfonyl-azide-free' (SAFE) protocol for producing diazo compounds from their active-methylene precursors via the Regitz diazo transfer reaction was developed and has displayed a remarkable substrate scope. It can be applied to generating arrays of diazo compounds for further evolution via combinatorial chemistry and a range of scaffold-generating transformations.

Rhodium(iii)-catalyzed sulfonamide directed ortho C-H carbenoid functionalization via metal carbene migratory insertion

A rhodium(iii)-catalyzed sulfonamide directed ortho C-H carbenoid functionalization has been developed with good yields. This method is attractive due to its broad substrate scope, and enables derivation of diverse biologically active sulfonamide structures and late-stage modification of sulfa drugs.

AUTOPHAGY ENHANCER AND USE THEREOF

Provided are a compound of chemical formula 1 or 2 and a use thereof. The compound can be advantageously used in the prevention or treatment of metabolic diseases including type 2 diabetes, insulin resistance, or obesity, on the basis of a mechanism of autophagy activation through the promotion of lysosome production.

Rhodium(III)-catalyzed C-C bond formation of quinoline N-oxides at the C-8 position under mild conditions

The Rh(III)-catalyzed C-8 selective direct alkylation and alkynylation of quinoline N-oxides has been developed. The reactions proceeded highly efficiently at room temperature over a broad range of substrates with excellent regioselectivity and functional group tolerance. This development demonstrates the synthetic utility of the N-oxide directing group as a stepping stone for remote C-H functionalization of quinolines.

Synthesis of α-diazo carbonyl compounds with the shelf-stable diazo transfer reagent nonafluorobutanesulfonyl azide

Nonafluorobutanesulfonyl azide is a shelf-stable, cost-effective and general diazo transfer reagent for the efficient synthesis of a-diazo carbonyl compounds in excellent yields and in very short reaction times, under mild conditions. The diazo products can be readily isolated in pure form after a simple aqueous extractive work-up that avoids chromatographic purification in most cases. Because of its high efficiency and wide substrate scope, shelf-stability, relatively low cost, and ease of product purification, nonafluorobutanesulfonyl azide offers an advantageous alternative to other commonly used diazo transfer reagents.

Flash vacuum pyrolysis of stabilised phosphorus ylides. Part 15. Generation of alkoxycarbonyl(sulfenyl)carbenes and their intramolecular insertion to give alkenyl sulfides

A range of 18 alkoxycarbonyl sulfinyl phosphorus ylides 9 have been prepared and their behaviour upon flash vacuum pyrolysis (FVP) at 600 deg C examined. For R1 = H, Me and Et they lose Ph3PO and in some cases Ph3P to give mixtures of products including the alkenyl sulfides 10, the sulfides 11, the disulfides 12 and the thioesters 14. The alkenyl sulfides 10 most likely arise from intramolecular insertion of the alkoxycarbonyl sulfenyl carbenes resulting from loss off Ph3PO to produce β-lactones which then lose CO2 and this is supported by the results from 13C labelled ylides. Possible mechanisms for the formation of 11 and 14 are also presented and the feasibility of various steps has been examined by preparation and pyrolysis of the proposed intermediates. In contrast, pyrolysis of the ylides 9 where R1 = Ph and the tert-butoxycarbonyl ylides 30 leads mainly to complete fragmentation with loss of Ph3PO and benzyl alcohol or 2-methylpropan-2-ol and does not give any useful sulfur-containing products. Four alkoxy-carbonyl sulfonyl diazo compounds 33 have been prepared and in three cases they give the alkenyl sulfones 34 upon FVP at 400 deg C, probably by an intramolecular insertion and decarboxylation process analogous to the formation of 10 from 9. On the other hand the alkoxycarbonyl carbenes produced by FVP of the amino acid-derived diazo compounds 35 undergo alternative proocesses with no sign of β-lactone formation. Fully assigned 13C NMR data are presented for 13 of the ylides.
