Synthesis and pharmacological evaluation of 1-Alkyl-N-[(1R)-1-(4- fluorophenyl)-2-methylpropyl]piperidine-4-carboxamide derivatives as novel antihypertensive agents

We synthesized and evaluated inhibitory activity against T-type Ca 2+ channels for a series of 1-alkyl-N- [(1R)-1-(4-fluorophenyl)-2- methylpropyl]piperidine-4-carboxamide derivatives. Structure-activity relationship studies have revealed that the isopropyl substituent at the benzylic position plays an important role in exerting potent inhibitory activity, and the absolute configuration of the benzylic position was found to be opposite that of mibefradil, which was first launched as a new class of T-type Ca2+ channel blocker. Oral administration of N- [(1R)-1-(4-fluorophenyl)-2-methylpropyl]-1-[2-(3-methoxyphenyl)ethyl] piperidine-4-carboxamide (17f) lowered blood pressure in spontaneously hypertensive rats without inducing reflex tachycardia, an adverse effect often caused by traditional L-type Ca2+ channel blockers.

Rapid Ti(Oi-Pr)4 facilitated synthesis of α,α,α-trisubstituted primary amines by the addition of Grignard reagents to nitriles under microwave heating conditions

A series of carbinamines (α,α,α-trisubstituted amines) have been prepared in a simple and efficient one-pot procedure by the addition of Grignard reagents to a series of aliphatic, aromatic and heteroaromatic nitriles. The resulting magnesium imines are subsequently converted to the desired amine after treatment with Ti(Oi-Pr)4 and additional microwave heating. Key to this procedure is the use of microwave heating for both steps of the reaction protocol, which significantly improves both reaction yields and reduces reaction times. In general, the Grignard addition reaction is complete within 5-10 min at 100 °C followed by conversion with Ti(Oi-Pr)4 and additional microwave heating to give the target amines in good yields.

One-pot synthesis of primary tert-alkylamines by the addition of organometallic reagents to nitriles mediated by Ti(Oi-Pr)4

A number of primary tert-alkylamines (18 examples, 25-72% yields) have been prepared according to a simple one-pot procedure by the addition of organometallic reagents such as Grignard reagents and organolithium compounds to nitriles in the presence of Ti(Oi-Pr)4. Georg Thieme Verlag Stuttgart.

Primary 1-Arylcyclopropylamines from aryl cyanides with diethylzinc and titanium alkoxides

(Matrix presented) 1-Aryl-substituted primary cyclopropylamines are conveniently prepared from aromatic nitriles and diethylzinc. The yields range from 40 to 56% for donor-substituted (five examples) to 62-82% for non- and acceptor-substituted substrates

Synthesis and Anticonvulsant Activity of 1-Phenylcyclohexylamine Analogues

Thirty-eight analogues of 1-phenylcyclohexylamine (PCA), a phencyclidine (PCP) derivative, were examined for their activities in the mouse maximal electroshock (MES) seizure test and in a motor-toxicity assay.In addition, we determined the binding affinities of the compounds for PCP acceptor sites in rat brain membranes labeled with -1-piperidine.Many of the analogues were protective against MES seizures (ED50s of 4-41 mg/kg, ip) and all of these compounds caused motor toxicity.The potencies in the motor toxicity and MES seizure tests showed a moderate correlation with the affinities for PCP sites.Several analogues exhibited a greater separation of potencies in the motor toxicity and MES seizure tests than did the parent compound PCA.These were obtained by (i) 3-methylation of the cyclohexyl ring trans to the phenyl ring, (ii) methoxylation at the ortho position on the phenyl ring, and (iii) contraction of the cyclohexane ring to form the corresponding cyclopentane.
