A series of new piperidine derivatives substituted in the 2-position has been prepared and tested pharmacologically. Most of these compounds have central stimulating effects, above all the 2-diphenylmethyl-piperidine hydrochloride.

The present 2-substituted imidazolines and 2-substituted-3,4,5,6-tetrahydropyrimidines possess valuable anti-depressant and anti-inflammatory properties. The compounds are prepared by the condensation of an appropriately substituted nitrile with a diamine. For example, condensation of 2-pyridylbenzyl cyanide with 1,2-ethylene diamine or with 1,3-propylene diamine produces a 2-(2-pyridylbenzyl) imidazoline or a 2-(2-pyridylbenzyl)-3,4,5,6-tetrahydropyrimidine.

Quaternary α-(hetero)arylnitriles are desirable biologically relevant products, however the existing methods for their synthesis can be unselective or require the use of undesirable reagents, such as cyanide salts. Herein we report a one-pot method for transnitrilation-mediated decyanation–metalation of disubstituted malononitriles, followed by treatment with (hetero)aryl electrophiles to access quaternary
