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.

In a document, author is Husain, Asif, Synthetic Route of 620-92-8.

Background: The prevalence of morbidity and mortality due to infections from parasitic worms and protozoa is on rise especially in third world countries. The situation is further worsened by drug resistant microbial pathogens. Objectives: The antimicrobial and anthelmintic activities associated with substituted furfuraldehyde and 1,8-naphthyridine nucleus of nalidixic acid prompted us to synthesize some new quinolone Schiff bases with an aim to obtain potent antibacterial and anthelmintic agents with improved safety and efficacy. Methods: A new series of 1,8 naphthyridine based Schiff bases were designed and synthesized by the reaction of Nalidixic acid methyl ester 1 with hydrazine hydrate in anhydrous condition which yielded 1-ethyl-1,4-dihydro-7-methyl-4-oxo-1,8-naphthyridine-3-carbohydrazide 2. The compound 2 was further treated with several furfural aldehydes to furnish the desired Schiff bases (3a-k). The in vitro antibacterial activity of Schiff bases was investigated against four Gram positive and four Gram negative bacterial strains. The newly prepared Schiff bases were also tested for their anthelmintic activity against Pheritima posthuma and Perionyx excavatus. Results: Chemical structures and identity of the prepared compounds were confirmed by their spectral data. Overall, Schiff bases (3a-k) showed good antimicrobial activity and interestingly five compounds exhibited more potent inhibitory effect than the standard drug Ampicillin against S. aureus, B. cereus, E. faecalis, S. epidermidis, E. coli, S. typhi and S. dysenteriae. Schiff bases also exhibited significant anthelmintic activity as indicated by their mean paralyses time (min) of 7.07-16.49, and 11.23-20.46 min against Perionyx excavatus and Pheritima posthuma in comparison to the 8.23 and 12.58 min shown by standard drug-Albendazole. Conclusion: It could be proposed that substitution of aromatic ring at C-5 of furfuryl heterocyclic ring in the Schiff bases produce compounds with promising antibacterial and anthelmintic actions.

In a document, author is Behlen, Michael J., introduce the new discover.

Dinickel naphthyridine-bis(oxazoline) catalysts promote enantioselective intermolecular [4 + 1]-cycloadditions of vinylidene equivalents and 1,3-dienes. The products of this reaction are methylenecyclopentenes, and the exocyclic alkene is generally obtained with high Z selectivity. E- and Z-dienes react in a stereoconvergent fashion, providing cycloadducts with the same sense of absolute stereochemistry and nearly identical ee values. This feature allows dienes that are commercially available as E/Z mixtures to be used as substrates for the cycloaddition. A DFT model for the origin of asymmetric induction is provided.

In a patnet, author is Javier Perez-Areales, Francisco, once mentioned the new application about 5089-22-5.

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.

In a document, author is Wang Wen-Zhen, introduce the new discover, Application of 92-70-6.

Based on the ligand (2,7-bis(alpha-pyrimidylamino)-1,8-naphthyridine (H(2)bpmany)), a linear pentachromium complex [Cr-5(mu(5)-bpmany)(4)Cl-2]PF6(1, mu(5)-bpmany = 2,7-bis(a-pyrimidylamino)-1,8-naphthyridine) was synthesized. The crystal structure of compound 1 has been characterized by X-ray crystallography. Interestingly, one metal atom in the center is missing in this linear chain, leading to the defective pentachromium metal string structure which is similar with the reported complex [Cr-5(mu(5)-dpznda)(4)Cl-2] (2, dpznda = N-2,N-7-di(pyrazin-2-yl)-1,8-naphthyridine-2,7-diamine). The central Cr(III) ion of 1 is eight-coordinated and is also rare in the chromium complex. The reaction of carbon dioxide with propylene oxide that generates propylene carbonate (PC) when catalyzed by [Cr-5(mu(5)-bpmany)(4)Cl-2]PF6 was investigated. Different reaction conditions including temperature and pressure were studied to optimize the reaction conditions.
