A regioselective one-pot synthesis of 2-substituted pyridine derivatives from N-alkoxycarboxylpyridinium salts and α-unsaturated organozinc compounds is described.Similarly, functional alkynyl organomagnesium compounds lead to 2-alkynyl-ω-functional pyridines, from which (E)-2-alkenyl or 2-alkyl-ω-functional pyridines can be obtained by partial or complete reduction.

The addition of the butenyl Grignard reagent to the unactivated double bond of 2-(α-methylallylic) aza aromatic compounds is completely regioselective giving the 2-(1,4-dimethyl-5 hexen-1-yl) aza aromatics in good yield.A preliminary coordination of magnesium atom to nitrogen atom and the formation of a six-center transition state involving the butenyl Grignard and the vinyl group has been proposed in order to explain the selectivity of the reaction.
