Cyclic cedrene acetals of the general formula A are described, in which the wavy lines represent the alpha - and beta -configurations, and R and R1 are the radicals below: <IMAGE> (A) R=R1=H R=H, R1=Me/R=Me, R1=H R=H, R1=Et/R=Et, R1=H R=H, R1=Pr/R=Pr, R1=H R=H, R1=Bu/R=Bu, R1=H R=H, R1=Iso-Bu/R=Iso-Bu, R1=H R=H, R1=Pentyl/R=Pentyl, R1=H R=H, R1=Iso-Pentyl/R=Iso-Pentyl, R1=H R=H, R1=Hexyl/R=Hexyl, R1=H R=R1=Me ( alpha , beta ) R=Me, R1=Fl/R=Et, R1=Me R=R1=Fl ( alpha , beta ) R=Me, R1=Pr/R=Pr, R1=Me R=Pt, R1=Pr/R=Pr, R=Et R=R1=Cyclobutyl R=R1=Cyclopentyl R=R1=Cyclohexyl.
