Affinity of 1-aryl-1,2,3,4-tetrahydroisoquinoline derivatives to the ion channel binding site of the NMDA receptor complex.

A series of 1-aryl-1,2,3,4-tetrahydroisoquinoline and 8-methyl-1-aryl-1,2,3,4-tetrahydroisoquinoline derivatives was evaluated for affinity to the PCP binding site of the NMDA receptor complex. The (S)-configured tetrahydroisoquinoline derivative (S)-4 e x HCl bearing a 2-methylphenyl substituent in position 1 of the heterocyclic ring system and a methyl group in position 8 was found to exhibit the highest affinity among the derivatives with a K(i)-value of 0.0374 microM. In addition, this compound shows a remarkable enantioselectivity of binding by being almost 90 times more potent than the corresponding (R)-enantiomer (R)-4 e x HCl. Additionally, a convenient and efficient synthetic approach to racemic 1-aryl-1,2,3,4-tetrahydroisoquinoline derivatives is described.

Diastereoselective alpha-alkoxylation of lactamide N-alkyl groups via intramolecular formation of oxonium ions as the key intermediate

Stereoselective introduction of an alkoxy group to the amine unit of lactamide derivatives, under electrochemical oxidation conditions, was investigated based upon the assumption that a cyclic oxonium ion can be formed between the alkoxy substituent on the chiral center and a carbocation generated at the alpha-position of N-alkyl substituents. With N-monosubstituted lactamides, diastereoselectivity in the N-alpha-alkoxylated product was not observed. With N,N-disubstituted lactamides, however, the selectivity appeared though in low ratios (?2.2). Requisite factors that govern the stereoselectivity, i.e. nucleophilicity of both internal and external nucleophiles and substitution on amine units, were also examined.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 166591-85-1 is helpful to your research. Application of 166591-85-1

Synthesis and antihypertensive activity of a series of 4-amino-6,7-dimethoxyquinazoline derivatives

A series of N2-[(acylamino)alkyl]-6,7-dimethoxy-2,4-quinazolinediamines was synthesized as potential alpha1-adrenoceptor antagonists. When administered to spontaneously hypertensive rats at 10 mg/kg po, a number of propanediamine derivatives showed good antihypertensive activity, whereas the ethanediamine derivatives, albeit being structurally more closely related to prazosin, were devoid of this property. The most active derivative, N-[3-[(4-amino-6,7-dimethoxy-2-quinazolinyl)methylamino]propyl]tetrahydro- 2-furancarboxamide hydrochloride, alfuzosin, showed high selectivity for peripheral alpha1-postjunctional adrenoceptors. At equiactive antihypertensive doses, its effect on the pressor response to postural changes in conscious dog was less marked than that shown by prazosin. In the light of these results, alfuzosin was selected for clinical evaluation.

Cobalt-catalyzed aerobic oxidative Povarov reaction of tertiary anilines with dihydrofuran for the synthesis of hexahydrofuroquinolines

A simple and efficient cobalt-catalyzed aerobic oxidative dehydrogenative Povarov reaction of tertiary anilines with dihydrofuran has been developed for the synthesis of hexahydrofuro[3,2-c]quinolines. The one-electron-oxidation involved reaction is performed under mild conditions and only requires simple cobalt salts as a catalyst and dioxygen as a terminal oxidant.

Oxidation-Induced beta-Selective C-H Bond Functionalization: Thiolation and Selenation of N-Heterocycles

Site-selective intermolecular C-H bond functionalization is of central importance to synthetic chemistry. In particular, direct beta-functionalization of N-heterocycles still remains a great challenge. Herein, we develop a strategy for oxidation-induced thiolation and selenation at the beta-position of piperidine derivatives and 1,2,3,4-tetrahydroisoquinoline via C-H bond functionalization. Various 4-sulfenylisoquinolines, 3-sulfenylpyridines, and 4-selenylisoquinolines can be obtained by using O2 as the only oxidant. Notably, neither a directing group nor a metal catalyst is necessary in this transformation. The preliminary mechanistic studies revealed that the oxidation and rearrangement pathway were key steps in this transformation, which provides a meaningful strategy for controlling site selectivity in the beta-functionalization of N-heterocycles.

Contrary to the accepted convention, this work shows that Minisci-type C-H alkylation does not require any metal, photocatalyst, light, or prefunctionalization of the readily available and inexpensive carboxylic acids to proceed well under mild conditions. These mild conditions can be utilized for late-stage alkylations of complex molecules, including pharmaceutical compounds and light-sensitive compounds which degrade under photocatalytic conditions.
