Dimethyl 2,6-dimethyl-4-(3-phenyl-1H-pyrazol-4-yl)-1,4-dihydropyridine-3,5-dicarboxylate
In the title compound, C20H21N3O4, the 1,4-dihydropyridine ring adopts a boat conformation. An intramolecular C—H...O hydrogen bond generates an S(6) ring motif. The pyrazole ring makes dihedral angles of 87.81 (7) and 45.09

Voltammetric behavior of 1,4‐dihydropyridine calcium antagonists [PDF]
The anodic electrochemical behavior of the five members of the 1,4‐dihydropyridine calcium antagonists family was studied. In all of the studied compounds (nifedipine, nitrendipine, nimodipine, nicardipine, and furaldipine), the oxidation process reveals

Antileishmanial and Antitoxoplasmal Activities of 1,4-dihydropyridines
We have synthesized 24 1,4-dihydropyridine compounds (1,4-DHPs) with different substituents at the aromatic ring by microwave-assisted one-pot Hantzsch multicomponent reaction and evaluated their in vitro activities against Toxoplasma gondii and Leishmania major. We have found that compound 9 ((±)-ethyl 2,7,7-trimethyl-4-(2-nitrophenyl)-5-oxo-1,4,5,6,7,

The intramolecular nitrile oxide olefin [3 + 2]‐cycloaddition offers a reliable entry toward 2‐aza‐bicyclo[4.3.0]‐nonanes, a substructure found in several bioactive piperidine alkaloids. The required oxime precursors were prepared in non‐racemic form by Ir‐catalyzed asymmetric allylation and ring‐closing metathesis.
