Article abstract of DOI:10.1016/S0040-4039(00)80617-6

A one-pot approach to 6-membered heterocyclic rings combines two 1,3-dipole equivalents: 2-azaallyl anions(2) and iodosilane 3.The resulting cis-2,6-disubstituted 4-methylenepiperidines are converted in high yield to 2,4,6-trisubstituted pyridines (6) by oxidation with mercuric acetate in acetic acid.
