    Asymmetric 4-aryl-1, 4-dihydro-2, 6-dimethyl-3, 5-pyridinedicarboxylates with a 2-ethylenedioxypropyl, 2-oxopropyl, or cyclopropylmethyl group as the ester moiety and related derivatives were synthesized and tested for vasodilating activity in anesthetized open-chest dogs and for antihypertensive activity in conscious spontaneously hypertensive rats. Cyclopropylmethyl methyl 1, 4-dihydro-2, 6-dimethyl-4-(3-nitrophenyl)-3, 5-pyridinedicarboxylate (5f, MPC-2101) and methyl 2-oxopropyl 1, 4-dihydro-2, 6-dimethyl-4-(2-nitrophenyl)-3, 5-pyridinedicarboxylate (8i, MPC-1304) exhibited potent cerebral vasodilating and antihypertensive activities, respectively. The maximum increase of vertebral blood flow after intravenous administration at 3.0 μg/kg was 221.4% for 5f, compared with 187.0 and 166.3% for nifedipine and nicardipine hydrochloride, respectively. The maximum falls of systolic blood pressure after oral administration of 8i at 0.3 and 1.0 mg/kg were 42.2 and 54.0 mmHg, while those of nifedipine, nicardipine, and hydralazine hydrochloride at 3.0 mg/kg were 23.3, 16.8, and 24.5 mmHg, respectively. The durations of significant vasodilating and antihypertensive effects for 5f and 8i were longer than those of nifedipine and nicardipine.

    Condensation of aromatic (heteroaromatic) aldehydes with 1,3-dicarbonyl compounds under the 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim][BF4]) ionic liquid-piperidinium acetate catalytic system (0.2 equiv. of each component) in the absence of a solvent affords, depending on the structures of the reagents, 2-arylidene derivatives of methyl acetoacetate and acetylacetone, diethyl 2,4-bis(trifluoroacetyl)-3-phenylpentanedioate, or dimethyl 2-aryl-4-hydroxy-6-oxocyclohexane-1,3-dicarboxylates. The reactions of the resulting 2-arylidene derivatives with O-methylisourea in the [Bmim][BF4] ionic liquid produced methyl 2-methoxy-4-methyl-6-aryldihydropyrimidine-5-carboxylates and 1-(2-methoxy-4-methyl-6-phenyldihydropyrimidin-5-yl)ethanone (mixtures of 3,6- and 1,6-dihydro isomers), which were transformed into the corresponding 3,4-dihydropyrimidin-2(1H)-one derivatives.

    Multicomponent reaction of benzylidenemalononitrile, 2-acetyl-3-arylacrylates, and aqueous ammonia in alcohols at room temperature proceeds stereoselectively to give (4RS,6SR)-4,6-diaryl-5,5-dicyano-2-methyl-1,4,5,6-tetrahydropyridine-3-carboxylates in 55–87% yields.
