1-[2-(Adamantan-1-yl)-2-hydroxyethyl]-1,2,3,6-tetrahydropyridines were obtained by reduction of 1-[(adamantan-1-yl)-2-oxoethyl]-pyridinium bromides. By the action of trifluoromethanesulfonicacid, they undergo carbocationic intramolecular cyclization accompanied by the Wagner–Meerwein rearrangement with the formation of substituted 1-azabicyclo[3.3.1]non-3-enes annulated with the homoadamantane framework
