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.
Aromatic electrophilic substitution of aromatic/electron rich heteroaromatic compounds with AlBr3 activated aldehydes/ketone to afford pyridyl aryl/heteroaryl or diaryl carbinols is described. The strong electron donating group dictates the regiochemical outcome of the product.

Although pyridine derivatives are versatile supporting ligands in catalysis, the development of their chiral versions has been relatively limited. Herein, we report the design, synthesis, and proof-of-concept application of a structurally tunable chiral pyridine framework featuring an annulated compact ring system. Using an N,B-bidentate ligand skeleton containing the chiral pyridine moiety, we have
