Coumarin 1,4-Dihydropyridine Derivatives

Bioorganic & Medicinal Chemistry, 1998
A series of 1,4-dihydropyridines bearing a coumarin moiety in 4-position was synthesized. The compounds were evaluated for inotropic, chronotropic and calcium antagonist activities. The replacement of the o-nitrophenyl moiety of nifedipine with a coumarin or phenylcoumarin system is accompanied by a decrease of the activity on myocardial and vascular ...

Iodocyclization of 1,4-dihydropyridines

Tetrahedron Letters, 1998
Abstract Iodine (or related species) addition to 1,4-dihydropyridines, with properly attached substituents at the nitrogen atom, leads to the corresponding 3-iodotetrahydropyridinium ions, which undergo an internal nucleophilic attack to furnish regio- and stereoselectively iodobi(poly)lteterocyclic ring systems in good yields.
