Facile synthesis of 5-To 7-membered benzolactam compounds via strongly facilitated electrophilic aromtic substitution reaction

We employed our system to activate aromatic ring-Tethered carbamate compounds with trifluoromethanesulfonic acid to obtain benzolactams with 5-To 7-membered rings, and examined the substrate scope and limitations of this activation method. In 5-membered ring formation, a halogen group on the aromatic ring did not greatly affect the reaction yield, but other electron-donating groups inhibited the cyclization reaction, and various side-reactions occurred. In 7-membered ring formation, eletron-donating groups on aromatic ring promoted the cyclization reaction, but cyclization of electron-deficient aromatic rings did not proceed well. The 6-membered ring formation reaction showed the greatest substrate generality.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 22246-12-4, help many people in the next few years.22246-12-4

Predictive three-dimensional quantitative structure-activity relationship of cytochrome P450 1A2 inhibitors

The purpose of this study was to determine the cytochrome P450 1A2 (CYP1A2) inhibition potencies of structurally diverse compounds to create a comprehensive three-dimensional quantitative structure-activity relationship (3D-QSAR) model of CYP1A2 inhibitors and to use this model to predict the inhibition potencies of an external set of compounds. Fifty-two compounds including naphthalene, lactone and quinoline derivatives were assayed in a 96-well plate format for CYP1A2 inhibition activity using 7-ethoxyresorufin O-dealkylation as the probe reaction. The IC50 values of the tested compounds varied from 2.3 muM to over 40 000 muM. On the basis of this data set, a comparative molecular field analysis (CoMFA) and GRID/ GOLPE models were created that yielded novel structural information about the interaction between inhibitory molecules and the CYP1A2 active site. The created CoMFA model was able to accurately predict inhibitory potencies of several structurally unrelated compounds, including selective inhibitors of other cytochrome P450 forms.

Iron catalyzed cross coupling reactions of aromatic compounds

A process for the production of compounds Ar?R1 by means of a cross-coupling reaction of an organometallic reagent R1?M with an aromatic or heteroaromatic substrate Ar?X catalyzed by one or several iron salts or iron complexes as catalysts or pre-catalysts, present homogeneously or heterogeneously in the reaction mixture. This new invention exhibits substantial advantages over established cross coupling methodology using palladium- or nickel complexes as the catalysts. Most notable aspects are the fact that (i) expensive and/or toxic nobel metal catalysts are replaced by cheap, stable, commercially available and toxicologically benign iron salts or iron complexes as the catalysts or pre-catalysts, (ii) commercially attractive aryl chlorides as well as various aryl sulfonates can be used as starting materials, (iii) the reaction can be performed under ?ligand-free? conditons, and (iv) the reaction times are usually very short.

Synthesis and structure-activity relationships of potential anticonvulsants based on 2-piperidinecarboxylic acid and related pharmacophores

Using N-(2,6-dimethyl)phenyl-2-piperidinecarboxamide (1) and N-(alpha-methylbenzyl)-2-piperidinecarboxamide (2) as structural leads, a variety of analogues were synthesised and evaluated for anticonvulsant activity in the MES test in mice. In the N-benzyl series, introduction of 3-Cl, 4-Cl, 3,4-Cl2, or 3-CF3 groups on the aromatic ring led to an increase in MES activity. Replacement of the alpha-methyl group by either i-Pr or benzyl groups enhanced MES activity with no increase in neurotoxicity. Substitution on the piperidine ring nitrogen led to a decrease in MES activity and neurotoxicity, while reduction of the amide carbonyl led to a complete loss of activity. Movement of the carboxamide group to either the 3- or 4-positions of the piperidine ring decreased MES activity and neurotoxicity. Incorporation of the piperidine ring into a tetrahydroisoquinoline or diazahydrinone nucleus led to increased neurotoxicity. In the N-(2,6-dimethyl)phenyl series, opening of the piperidine ring between the 1- and 6-positions gave the active norleucine derivative 75 (ED50 = 5.8 mg kg-1, TD50 = 36.4 mg kg-1, PI = 6.3). Replacement of the piperidine ring of 1 by cycloalkane (cyclohexane, cyclopentane, and cyclobutane) resulted in compounds with decreased MES activity and neurotoxicity, whereas replacement of the piperidine ring by a 4-pyridyl group led to a retention of MES activity with a comparable PI. Simplification of the 2-piperidinecarboxamide nucleus of 1 into a glycinecarboxamide nucleus led to about a six-fold decrease in MES activity. The 2,6-dimethylanilides were the most potent compounds in the MES test in each group of compounds evaluated, and compounds 50 and 75 should be useful leads in the development of agents for the treatment of tonic-clonic and partial seizures in man.
