A novel method for the synthesis of cyanomethylated tetrahydroisoquinolines has been developed with mild reaction conditions, good yields and a broad substrate scope. Acetonitrile, a common solvent, is for the first time used as a pronucleophile for this type of two sp3C?H bonds cross-dehydrogenative coupling (CDC) reaction. A new oxidative system (CuCl2/TEMPO/Cs2CO3) has been established by our group, in which the mild TEMPO reagent was found to be a highly efficient oxidant. (Figure presented.).

A series of isoquinolines, N-methyl-1,2-dihydroisoquinolines, N-methyl-1,2,3,4-tetrahydroisoquinolines, 1,2,3,4-tetrahydroisoquinolines, and N-methylisoquinolinium ions were tested as inhibitors of monoamine oxidase A and B. All compounds were found to act as reversible and time-independent MAO inhibitors, often with a distinct selectivity towards MAO-A. As a class, the N-methylisoquinolinium ions were found to be the most active MAO-A inhibitors, with N-methyl-6-methoxyisoquinolinium ion emerging as a potent (IC50 = 0.81 muM) and competitive MAO-A inhibitor. Comparative molecular field analysis (CoMFA, a 3-D-QSAR method) of MAO-A inhibition was performed using the data reported here and in the literature. Using the steric and lipophilic fields of the inhibitors, quantitative models with reasonable predictive power were obtained that point to the importance of steric, lipophilic, and polar interactions in modulating MAO-A inhibitory activity.

Herein we report a convenient, fast, and high-yielding method for the generation of the racemic amide anaesthetics mepivacaine, ropivacaine, and bupivacaine. Coupling of alpha-picolinic acid and 2,6-xylidine under sealed-vessel microwave conditions generates the intermediate amide after a reaction time of only 5 min at 150 C. Subsequent reaction in a continuous-flow high-pressure hydrogenator (H-Cube ProTM) in the presence of the respective aldehyde directly converts the intermediate to the final amide anaesthetics in a continuous, integrated, multi-step ring-hydrogenation/reductive amination protocol. Merits and limitations of the protocol are discussed.

A series of 1,2,3,4-tetrahydroisoquinolines, tetrahydrothieno[2,3-c]pyridines, and related compounds were evaluated for their ability to inhibit binding of [3H]-1-[1-(2-thienyl)piperidine and [3H]-N-allylnormetazocine to phencyclidine (PCP) and sigma receptors, respectively. A representative series of compounds was evaluated in behavioral assays to determine the ability of the compounds to induce PCP-like stereotyped behavior and ataxia. All of the compounds caused stereotyped behavior and ataxia, indicating their agonist actions at the PCP site.

Isoquinoline derivatives structurally related to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) or 1-methyl-4-phenylpyridinium (MPP+) may be endogenous neurotoxins causing nigral cell death in Parkinson’s disease. These compounds inhibit mitochondrial function but, like MPP+, require accumulation in dopaminergic neurones via the dopamine reuptake system to exert toxicity. We, now, examine the substrate affinity of 14 neutral and quaternary isoquinoline derivatives (7 isoquinolines, 2 dihydroisoquinolines and 5 1,2,3,4-tetrahydroisoquinolines) for the dopamine reuptake system by their ability to inhibit the uptake of [3H]dopamine into rat striatal synaptosomes. Ten isoquinoline derivatives and MPP+ inhibited [3H]dopamine uptake in a concentration-dependent manner. Only 5 isoquinoline derivatives produced 50% inhibition of [3H]dopamine uptake (IC50 = 8.0-50.0 muM), none of which were as potent as MPP+ (IC50 = 0.33 muM). These findings suggest that isoquinoline derivatives are moderate to poor substrates for the dopamine reuptake system and that high concentrations of, or prolonged exposure to, isoquinoline derivatives may be necessary to cause neurodegeneration.

Conformationally constrained, 1,2,3,4-tetrahydroisoquinoline (TIQ) analogs of central stimulant (e.g. amphetamine) and hallucinogenic (e.g. DOM) phenylalkylamines were prepared and evaluated to determine the contribution to activity of this conformational restriction. The amphetamine-related TIQs failed to produce locomotor stimulation in mice and did not produce amphetamine-appropriate responding in tests of stimulus generalization in (+)amphetamine-trained rats. Hallucinogen-related TIQs lacked appreciable affinity for 5-HT2A serotonin receptors and did not produce DOM-like effects in tests of stimulus generalization in DOM-trained rats. It is concluded that the phenylalkylamine conformation represented by the TIQs is not a major contributor to these actions.

Methyl-selective alpha-oxygenation of tertiary amines is a highly attractive approach for synthesizing formamides while preserving the amine substrate skeletons. Therefore, the development of efficient catalysts that can advance regioselective alpha-oxygenation at the N-methyl positions using molecular oxygen (O2) as the terminal oxidant is an important subject. In this study, we successfully developed a highly regioselective and efficient aerobic methyl-selective alpha-oxygenation of tertiary amines by employing a Cu/nitroxyl radical catalyst system. The use of moderately hindered nitroxyl radicals, such as 1,5-dimethyl-9-azanoradamantane N-oxyl (DMN-AZADO) and 1-methyl-2-azaadamanane N-oxyl (1-Me-AZADO), was very important to promote the oxygenation effectively mainly because these N-oxyls have longer life-times than less hindered N-oxyls. Various types of tertiary N-methylamines were selectively converted to the corresponding formamides. A plausible reaction mechanism is also discussed on the basis of experimental evidence, together with DFT calculations. The high regioselectivity of this catalyst system stems from steric restriction of the amine-N-oxyl interactions.
