Nucleophilic addition of diborylalkyl reagents to N-alkyl or N-acylpyridinium and related heteroarenium salts has been developed as a key step for the synthesis of nonaromatic nitrogen heterocycles that contain contiguous stereogenic centers. Derivatization of the dihydropyridine products for the synthesis of tetrahydropyridines and piperidines have also been described.
