Tandem Hydroamination/Cyclization Access to N-2(5H)-Furanone Derivatives for COX-2 Inhibitor

Abstract

Several N-2(5H)-furanone compounds were synthesized successfully and were characterized systematically. Compounds bearing piperazine and trifluoromethyl moieties 1q were the best COX-2 inhibitors with ultrahigh selectivity index compared to celecoxib.

Enhanced Visible-Light Photoelectrocatalytic Activity over a Polydiacetylene-Based Metal Complex with RGO Modified under Wastewater

“…The above-mentioned research work has been extensively devoted to investigate the effects of the polymerization degree/size of PDA on the performance of different semiconductors in either photovoltaic or photoelectrocatalytic applications. , However, it remains unclear whether the polymerization degree/size is beneficial or detrimental to the performance of the same semiconductor in photoelectric transfer and in photoelectrocatalysis. , A range of long chain-like PDA-based coordination complexes were prepared via self-assembly and electrophoretic deposition (EPD) (Scheme ). − Thus, this study aims to characterize the corresponding polymers as photoanodes for effective hydrogen generation through the PEC process, along with the investigation of its mechanism. The broad-wavelength CPs, which have proper energy levels and high efficiency charge-transfer properties, are in demand. , Plenty of building blocks are used for constructing CPs for the purpose of realizing the above-mentioned desirable characteristics simultaneously. , Not only that, PDA is also extraordinarily attractive owing to its conjugating plane structure, benefiting for charge separation and transport when incorporated into PDA. , Besides, bithiazole (BTz)-bridged CPs, containing a benzothiadiazole moiety, are witnessing a large number of usages, particularly photocatalytic H 2 production. , Thus, we introduced CPs into BTz, and the corresponding CPs were systematically displayed (Scheme ).…”
