1,4-Dihydropyridines bearing a pharmacophoric fragment of lidoflazine

Bioorganic & Medicinal Chemistry, 1996
A series of 1,4-dihydropyridines bearing a pharmacophoric fragment of lidoflazine was synthesized. The compounds were evaluated for inotropic, chronotropic, and calcium antagonist activities. All compounds behave as inotropic and chronotropic agents, except for compounds 4b, 5a, and 5b, which exhibit a rather weak calcium antagonism in vascular smooth ...

Vicinal diamination of 1,4-dihydropyridines

Chemical Communications, 1998
Electrophilic interaction of iodine with N-alkyl-1,4-dihydropyridines 1 in the presence of secondary amines stereoselectively leads to the corresponding trans-2,3-diamino-1,2,3,4-tetrahydropyridines 2 in satisfactory yields (79–94%); the method allows the synthesis of piperidine, pyrrolidine, morpholine and piperazine derivatives.

The alkylation of hantzsch 1,4‐dihydropyridines

Journal of Heterocyclic Chemistry, 1986
AbstractThe reaction of carbanions derived from Hantzsch 1,4‐dihydropyridines with alkyl halides was studied and methods for mono‐ and di‐alkylation were devised.
