The invention relates to new tetrahydropyridine derivatives, processes for preparing them and their use as pharmaceutical compositions with cholinomimetic properties.
cobalt-catalyzed enantioconvergent radical Negishi C(sp3)–C(sp2) cross-coupling of racemic benzyl chlorides with arylzinc reagents has been developed in good yield with moderate enantioselectivities. This strategy provides an expedient access toward a range of enantioenriched 1,1-diarylmethanes. Key to this discovery is the utilization of a chiral multidentate anionic N,N,P-ligand to strongly coordinate with the
versatile feedstocks in synthetic chemistry, widely existing in drug molecules and natural products. Herein, we disclose a nickel-catalyzed formal aminocarbonylation of secondary benzylchlorides with isocyanides yielding α-substituted phenylacetamide with steric hindrance, which is synthetically challenging via palladium-catalyzed aminocarbonylation. The reaction features wide functional group tolerance
