Azole-N-acetonitrile derivatives were utilized as synthons for an ambident carbonyl moiety via a strategy relying upon sequential base-mediated S NAr substitution of a 2-halo heterocycle, in situ oxidation, and amine displacement. This strategy allows prompt and efficient synthesis of N-containing heteroaryl amides directly from the corresponding halides via a one-pot process.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C8H5ClN2, you can also check out more blogs about1448-87-9

The pair NaBH4-TMEDA as hydride source and a palladium catalyst in THF prove to be an efficient system for the hydrodehalogenation of halogenated heterocycles with one or more heteroatoms. In general, Pd(OAc) 2-PPh3 rapidly hydrodehalogenates reactive halo-heterocycles such as bromo-pyridines, -quinolines, -thiophenes, -indoles, -imidazoles, etc., at room temperature in very good yields, whereas in most cases PdCl2(dppf) reduces less reactive halides such as chloro-pyridines, -quinolines, -pyrimidines and bromo-indoles, -benzofurans, etc. Moreover, PdCl2(tbpf) shows to be even more active removing the 2- and 5-chlorine from both thiophene and thiazole rings. The reaction conditions tolerate various functional groups, allowing highly chemoselective reactions in the presence of halide, ester, alkyne, alkene and nitrile substituents. Moreover, with a proper selection of the catalyst it is also possible to obtain a good control in the regioselective hydrodehalogenation of a variety of polyhalogenated substrates.

A series of penta-1,4-dien-3-one oxime ether derivatives containing a quinoxaline moiety were synthesized and their antibacterial and antiviral activities were evaluated. Bioassay activity indicated that some of the compounds displayed significant antibacterial and antiviral activities. In particular, some title compounds were found to show remarkable antiviral activities against tobacco mosaic virus (TMV). Compound 6i showed remarkable curative, protective and inactivation activity against TMV, with a 50% effective concentration (EC50) of 287.1, 157.6 and 133.0 mug mL-1, respectively. These results were better than or comparable to those of ningnanmycin (356.3, 233.7 and 121.6 mug mL-1, respectively). Microscale thermophoresis (MST) also showed that the binding of compound 6i to TMV coat protein (TMV-CP) gave a Kd value of 0.115 ± 0.092 mumol L-1, which was better than that of ningnanmycin (0.523 ± 0.254 mumol L-1). Meanwhile, the EC50 values of compound 6k against Xanthomonas axonopodis pv. Citri (Xac) and Xanthomonas oryzae pv. oryzae (Xoo) were 16.8 and 33.4 mug mL-1 respectively, and that of compound 6i against Ralstonia solanacearum (Rs) was 33.9 mug mL-1. These results were better than those of bismerthiazol (44.3, 42.5 and 62.4 mug mL-1, respectively). The mechanism of antibacterial action of compound 6k against Xac was analysed through scanning electron microscopy (SEM). This study indicated that the title compounds are valuable in the search for novel agrochemicals.
