Production of bicyclic enol ether (I) (n = 3-12; R 1 , R 2 , R '= H, C 1 -C 4 alkyl) by radical addition of CHR' = CR 2 -CHR 3 -OR 4 (III; R '= tert.- Butyt; tetrahydrofuran-2-yl; tetrahydropyran-2-yl) to a cyclic ketone (IV) and subsequent acid-catalyzed cyclization. New connections II I and II are intermediates for the synthesis of musky fragrances. |
