Visible-Light-Induced ortho-Selective Migration on Pyridyl Ring: Trifluoromethylative Pyridylation of Unactivated Alkenes

The photocatalyzed ortho-selective migration on a pyridyl ring has been achieved for the site-selective trifluoromethylative pyridylation of unactivated alkenes. The overall process is initiated by the selective addition of a CF3 radical to the alkene to provide a nucleophilic alkyl radical intermediate, which enables an intramolecular endo addition exclusively to the ortho-position of the pyridinium salt. Both secondary and tertiary alkyl radicals are well-suited for addition to the C2-position of pyridinium salts to ultimately provide synthetically valuable C2-fluoroalkyl functionalized pyridines. Moreover, the method was successfully applied to the reaction with P-centered radicals. The utility of this transformation was further demonstrated by the late-stage functionalization of complex bioactive molecules.

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.SDS of cas: 1532-72-5, you can also check out more blogs about1532-72-5

The Synthesis of Indolizidine and Quinolizidine Ring Systems by Free Radical Cyclization of 4-Aza-6-methoxycarbonyl-5-hexenyl Radicals

The formation of bicyclic amines by the intramolecular cyclization of 4-aza-6-methoxycarbonyl-5-hexenyl radicals is described.The direct attachment of a nitrogen atom to the double bond changes the electronic nature of the alkene such that the cyclization is less efficient than the all carbon analogue or the other aza-substituted 5-hexenyl cyclizations.The reaction has been used in a short, convenient synthesis of a variety of indolizidines from methyl nicotinate.In addition, the cyclization was used as the key step in a short synthesis of (+/-)-epilupinine from methyl nicotinate.

Tyrosine kinase inhibitors. 5. Synthesis and structure-activity relationships for 4-[(phenylmethyl)amino]- and 4-(phenylamino)quinazolines as potent adenosine 5′-triphosphate binding site inhibitors of the tyrosine kinase domain of the epidermal growth factor receptor

A series of 4-substituted quinazolines and related compounds have been prepared and evaluated for their ability to inhibit the tyrosine kinase activity of the epidermal growth factor receptor on a phospholipase C-gamma1- derived substrate. The results show a narrow structure-activity relationship (SAR) for the basic ring system, with quinazoline being the preferred chromophore and benzylamino and anilino the preferred side chains. In the 4- anilino series, substitution on the 3-position of the phenyl ring with small lipophilic electron-withdrawing groups provided analogues with enhanced potency. Two series of compounds [4-(phenylmethyl)amino and 4-(3- bromophenyl)amino] were studied to determine SARs for quinazoline substituents. In the more active 4-(3-bromophenyl)amino series, electron- donating groups (NH2, OMe) at the 6- or 7-position increased activity, in a pattern consistent with a requirement for high electron density in the vicinity of the 8-position of the quinazoline ring. The 6,7-dimethoxy derivatives were the most effective in both series, with the 4-(3- bromophenyl)amino derivative (3) having an IC50 of 0.029 nM, making it by far the most potent reported inhibitor of the tyrosine kinase activity of the epidermal growth factor receptor enzyme.

Synthesis and deprotonation of 2-(halophenyl)pyridines and 1-(halophenyl)isoquinolines

The ability of the 2-pyridyl and 1-isoquinolyl groups to direct metalation was studied in the benzene series. For this purpose, 2-(halophenyl)pyridines and 1-(halophenyl)isoquinolines were prepared. Interestingly, nucleophilic addition reactions on the azine ring were not observed under kinetic control using butyllithium, and the substrates were cleanly deprotonated on the benzene ring: the azine ring acidifies the adjacent hydrogen H2 (N-H2 interaction through space and/or inductive electron-withdrawing effect) and probably favors the approach of butyllithium (chelation). Under thermodynamic conditions using lithium dialkylamides, the presence of the azine group makes the lithio derivative at C2? more stable (chelation and/or inductive electron-withdrawing effect). This was evidenced in two ways: (1) syntheses of 2-halophenyllithiums (F, Cl, Br) substituted at C6 by a 2-pyridyl or 1-isoquinolyl group without elimination of lithium halide and (2) iodine migration from C2? to C4? when treating 2-(3-halo-2-iodophenyl) pyridines or 1-(3-fluoro-2-iodophenyl)isoquinoline with LTMP. Comparisons between the 2-pyridyl and fluoro units showed the latter was the stronger directing group for deprotonation.

Effects of heartwood extractives on symbiotic protozoan communities and mortality in two termite species

Lower termites (Isoptera: Rhinotermitidae) are considered severe pests of wood in service, crops and plantation forests. Termites mechanically remove and digest lignocellulosic material as a food source. The ability to digest lignocellulose not only depends on their digestive tract physiology, but also on the symbiotic relationship between termites and their intestinal microbiota. The current study was designed to test the possible effects of four heartwood extractives (Tectona grandis, Dalbergia sissoo, Cedrus deodara and Pinus roxburghii) on the mortality, feeding rate and protozoan population in two lower termites, Reticulitermes flavipes and Heterotermes indicola. All wood extractives tested rapidly lowered protozoan numbers in the hindgut of termite workers, which was closely correlated with worker mortality. The average population of protozoans in both termite species was diminished in a dose-dependent manner after fifteen days feeding on treated filter paper. Mortality of termites increased when fed on filter paper treated with T. grandis or D. sissoo heartwood extractives with minimum feeding rate at the maximum concentration (10 mg ml?1). Protozoan number and termite survival was also compared with starved termites and results showed that protozoan populations ware reduced up to 99.60 and 65.71% in R. flavipes and H. indicola, respectively as compared to untreated filter paper controls with ? 80% survival for both termite species. Characterizations of heartwood extractives were performed using Gas Chromatography-Mass spectrometry (GC-MS) and chemical profiles were obtained for extractives from each wood species. The largest chemical components, based on percentage of sample, identified from T. grandis were Squalene, 2-methyl-9, 10-Anthracenedione and 1-Methyl-3,4-dihydroisoquinoline. Trismethoxyresveratrol, 1, 3-Diamino-8-n-butyl-5, 6 dihydrobenzoquinazoline and 6, 8-dimethyl-Benzanthracene were the largest components from D. sissoo. The largest percentage components from C. deodara were (E) ? Atlantone, Di-epi-alpha-cedrene and alpha-Cuprenene. The main components of P. roxburghii were identified as 1, 2, 3, 4-tetrahydro-5, 8-dimethyl-Acridin-9-amine, 2, 3-dihydro-5, 7-dihydroxy-2phenyl-4H-1-Benzopyran-4-one and 5-hydroxy-7-methoxy-2-phenyl4H-1-Benzopyran-4-one. These are discussed in terms of their termiticidal and protozoicidal properties.
