Electric Literature of C5H7Br. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 1-Bromo-2-pentyne, is researched, Molecular C5H7Br, CAS is 16400-32-1, about Distal Alkenyl C-H Functionalization via the Palladium/Norbornene Cooperative Catalysis. Author is Wu, Zhao; Fatuzzo, Nina; Dong, Guangbin.

A distal-selective alkenyl C-H arylation method was reported through a directed palladium/norbornene (Pd/NBE) cooperative catalysis. An usage of appropriate combination of the directing group and the NBE cocatalyst was the key feature of this method. A range of acyclic and cyclic cis-olefins were suitable substrates and the reaction was operated under air with excellent site-selectivity. Preliminary mechanistic studies were consistent with the proposed Pd/NBE-catalyzed C-H activation instead of the Heck pathway. Initial success on distal alkylation was achieved using MeI and Me bromoacetate as electrophiles.

Compounds were prepared with heterocyclic replacements for metabolically unstable esters of benzopyranyl indole-2-carboxylic esters, which showed good in vitro and in vivo cardioprotective efficacies possibly through the opening of mitochondrial ATP-sensitive potassium channel (KATP). Initially, indolin-2-yl-heterocycles were constructed using unprotected indoline-2-carboxylic acid, but the cyclization was proceeded with oxidation of the indoline ring to the indole, which did not react with benzopyranyl epoxide. An N-BOC group was introduced to deplete the electron d. of the indoline ring. Various indolin-2-yl-heterocycles, such as I and II, were prepared by the cyclization of the building blocks including carboxamide, β-hydroxy amide, hydrazide, nitrile starting from N-BOC-indoline-2-carboxylic acid.

Nagy, P. I.; Tokarski, John; Hopfinger, A. J. published the article 《Molecular Shape and QSAR Analyses of a Family of Substituted Dichlorodiphenyl Aromatase Inhibitors》. Keywords: dichlorodiphenyl aromatase inhibitor QSAR.They researched the compound: 1-(Bis(4-chlorophenyl)methyl)piperazine( cas:27469-61-0 ).Name: 1-(Bis(4-chlorophenyl)methyl)piperazine. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:27469-61-0) here.

Conformational analyses of three families of substituted dichlorodiphenyl aromatase inhibitors indicated that both potent and weak inhibitors adopt a common global min. energy conformation. Further, this global min. energy conformation is the only meaningful intramol. conformer state that can be energetically realized and is virtually identical to the crystal structure of one of the analogs. Quant. structure-activity relationships, QSARs, were sep., and jointly, developed for two series of inhibitors. The distance, D, of a nitrogen atom in the variable heterocyclefrom the core Cc atom is the most important activity descriptor. The optimum distance between the nitrogen and Cc to maximize inhibitor potency is about 3.6 Å for both classes of analogs. Integrated potential energy field difference calculations were also carried out using a proton probe and some of the variable heterocycles. The field calculations coupled with the QSAR studies suggest that the nitrogen 3.6 Å from Cc acts as a hydrogen bond acceptor. Two possible three-dimensional pharmacophores are proposed for effective aromatase inhibitors.
