A double Hofmann elimination of a bis(tetrahydropyridinium) salt, prepared from simple pyridine derivatives in six steps, afforded stereoselectively a tetraene [(2E,4E,8Z)-2,8-bis(dimethylaminomethyl)-2,4,8,10-undecatetraen-1-ol], which was further transformed in six steps into a C7-C17 model system of avermectins and milbemycins.
