The oxidative dearomatization of anilines was combined with a domino Michael addition, providing a series of nitrogen-containing bridged bicyclic compounds in moderate to excellent yields. The bridged bicyclic compound could be converted into the corresponding meta carbon-functionalized aniline derivative via a quinine-catalyzed tandem retro-oxa-Michael addition–aromatization reaction.

In this study, twelve hexahydroquinoline derivatives which are condensed analogs of the 1,4‐DHP molecule were synthesized and evaluated for their calcium‐antagonistic activity. The results indicated that all compounds and nifedipine produced concentration‐dependent relaxation in rabbit gastric fundus smooth muscle strips. The relaxant effects of the compounds on the tissues were expressed as percentage

by the Hantzsch reaction and screened for their myorelaxant and potassium channel opening activities. The maximum relaxant effects (E(max)) and pD(2) values on exogenous noradrenaline precontracted tissues and inhibitory effects on cholinergic neurotransmission of the compounds and pinacidil were determined on isolated strips of rabbitgastricfundus smooth muscle. Obtained results indicated that some

Nifedipineanalogs I, II and III with the 2H-1-benzopyran-2-one (coumarin) fluorophore linked at the 2, 2 and 6 and 4 positions of the dihydropyridine ring were synthesized by the modified Hantzch condensation procedures. Attempts to synthesize dihydropyridine with the fluorophore at position 3 (IV) were unsuccessful.
通过改进的Hantchch缩合方法合成了具有在二氢吡啶环的2、2、6和4位连接的2 H -1-苯并吡喃-2-酮(香豆素)荧光团的硝苯地平类似物I,II和III 。尝试在位置3(IV)处带有荧光团的二氢吡啶合成失败。

7-trimethyl-5-oxo-4-(disubstituted phenyl)-1,4,5,6,7,8-hexahydro-quinoline-3-carbohydrates and 12 new N-N-diethyl 2,6,6 or 2,7,7-trimethyl-5-oxo-4-(disubstituted phenyl)-1,4,5,6,7,8-hexahydroquinoline-3-carboxamide derivatives are synthesized and their activity on calcium channel antagonists was observed. Synthesis was done by the Hantzsch reaction. Calcium antagonistic activity was determined by tests
