Popis:	Organozinc reagents undergo nucleophilic addition to 5,6-dihydropyridinium ions with 1,2-versus 1,4-regioselectivity depending on the structure of the organic group and the presence of magnesium salts. Addition of organozinc reagents to 2-cyano-5,6-dihydropyridines, which are synthetic equivalents of 5,6-dihydropyridinium ions, gives exclusively 1,2-addition products
