Transition-metal-catalyzed C-H functionalization of aromatic secondary amides with alkynes mainly undergo C-H/N-H annulation but rarely undergo ortho-alkenylation. It is particularly challenging to selectively realize both oxidative annulation and ortho-alkenylation of aromatic secondary amides with alkynes in the transition-metal-catalysis. In this article, we synthesized fully-substituted 2-pyridones and 2,6-naphthyridine-1,5-diones via C(sp(2))-H functionalization of fumaramides for the first time. Under the Ru-catalysis, fumaramides and 1,2-diaryl ethynes first undergo C-H/N-H annulation leading to the intermediate 2-pyridone with an exocyclic secondary amide, and subsequently undergo the unexpected stereoselective C-H alkenylation to realize fully substituted 2-pyridones bearing an exocyclic anti alkenyl group. On the addition of K2CO3, however, the transformation of fumaramides with 1,2-dialkyl ethyne undergoes two conventional C-H/N-H annulations to provide 2,6-naphthyridine-1,5-diones in high yield. The two procedures can be successfully enlarged to gram-scales without erosion of the yields. In addition, some 2-pyridones and 2,6-naphthyridine-1,5-diones emitting clear ultraviolent and fluorescent light, indicating the potential utility of this work in organic light-emitting materials.

On the basis of the good anti-inflammatory properties shown by the 9-alkyl-N,N-dialkyl-5-(alkylamino)[1,2,4]triazolo[4,3-a][1,8]naphthyridine-6-carboxamides 1, a series of analogues of such compounds, in which the 9-alkyl substituent was replaced by an ester or amide group (compounds 3a-i), was prepared and tested (inhibition of carrageenan-induced paw edema in the rat). Also two 5-(N-alkylN-acylamino) derivatives (compounds 4a,b) were synthesized and evaluated for the same purpose. Even though the general trend for these new [1,2,4]triazolo[4,3-a][1,8]naphthyridine derivatives was a decrease in activity compared with compounds 1, some of the new synthesized compounds exhibited still good anti-inflammatory properties.

Aim: Simultaneous modulation of several key targets of the pathological network of Alzheimer’s disease (AD) is being increasingly pursued as a promising option to fill the critical gap of efficacious drugs against this condition. Materials & methods: A short series of compounds purported to hit multiple targets of relevance in AD has been designed, on the basis of their distinct basicities estimated from high-level quantum mechanical computations, synthesized, and subjected to assays of inhibition of cholinesterases, BACE-1, and A beta 42 and tau aggregation, of antioxidant activity, and of brain permeation. Results: Using, as a template, a lead rhein-huprine hybrid with an interesting multitarget profile, we have developed second-generation compounds, designed by the modification of the huprine aromatic ring. Replacement by [1,8]-naphthyridine or thieno[3,2-e] pyridine systems resulted in decreased, although still potent, acetylcholinesterase or BACE-1 inhibitory activities, which are more balanced relative to their A beta 42 and tau antiaggregating and antioxidant activities. Conclusion: Second-generation naphthyridine-and thienopyridine-based rhein-huprine hybrids emerge as interesting brain permeable compounds that hit several crucial pathogenic factors of AD.

The effect of structural modulation on a series of donor-acceptor (D-A) copolymers (1-7), comprising of thieno[3,2-b]thiophene (TT) donor and thiazole-flanked different bis-amide-functionalized acceptor units, has been explored. Structural functionalization has been performed by incorporating aromatic rings in the bis-amide-functionalized bipyrrolylidene-2,2 ‘(1H,1 ‘ H)-dione (BPD) (1) acceptor unit, and six D-A copolymers containing isoindigo (2), azaisoindigo (3), benzoisoindigo (4), benzoazaisoindigo (5), 1,5-naphthyridine-BPD (6), and 1,8-naphthyridine-BPD (7) as acceptor units are designed. Density functional theory has been employed to understand the impact of structural modulation on geometrical, optoelectronic, charge transport, and photovoltaic properties of the copolymers. The higher proportion of N-heteroatom in copolymers 3, 6, and 7 leads to low-lying highest occupied molecular orbital (lowest unoccupied molecular orbital) levels and thus improves their air stability and open-circuit voltage. The computed optical absorption in the visible range (602-754 nm) ensures that the studied compounds can efficiently harvest photon energy. The ratio of charge transfer rate (K-CT) and charge recombination rate (K-CR) at donor/PC61BM interfaces of structurally tuned copolymers are found to be similar to 10(7) to 10(22) times higher than 1/PC61BM. The maximum predicted power conversion efficiency by Scharber diagram could reach up to similar to 8% for 3, 6, and 7. The calculated results shed light on the fact that the structural modulation of bis-amide-functionalized D-A copolymers can efficaciously lead to enhanced air stability and photovoltaic performance.

The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. In an article, author is Wang, Yuan, once mentioned the application of 179324-87-9, Name is (R)-BoroLeu-(+)-Pinanediol trifluoroacetate. Now introduce a scientific discovery about this category, Recommanded Product: (R)-BoroLeu-(+)-Pinanediol trifluoroacetate.

Si-based solar cells have dominated the entire photovoltaic market, but remain suffering from low power conversion efficiency (PCE), partly because of the poor utilization of ultraviolet (UV) light. Europium(III) (Eu3+) complexes with organic ligands are capable of converting UV light into strong visible light, which makes them ideal light converter to increase the efficiency of solar cells. However, the low stability of such complexes seriously hampers their practical applications. In this work, we report a highly stable and luminescent ethylene-vinyl acetate (EVA) copolymer film consisting of a Eu3+ complex as a down-shift material, Eu (ND)(4)CTAC (ND = 4-hydroxy-2-methyl-1,5-naphthyridine-3-carbonitrile, CTAC = hexadecyl trimethyl ammonium chloride), coating of which onto the surface of large area polycrystalline silicon solar cells (active area: 110 cm(2)) results in an increase of PCE from 15.06% to 15.57%. Remarkable stability of the luminescent film was also demonstrated under light-soaking test for 500 h, and no obvious luminescence degradation can be observed. The remarkable enhancement of the conversion efficiency by 0.51% absolute on such a large active area, together with the high stability of the luminescent film, demonstrates a prospect for the implementation of the films in photovoltaic industry.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Welcome to check out more blogs about 179324-87-9, in my other articles.
