Abstract

New 1-acyl- and 1-hydroxymethyl-cyclododecanes and -cyclododecenes. The new 1-acyl-cyclododecenes and -cyclododecanes are obtained by a Rupe or Meyer-Schuster rearrangement, with or without subsequent hydrogenation in the presence of Ni, Pd and Pt catalysts. The 1-acyl-cyclododecenes and -cyclododecanes are valuable scents of the basic type of the sought-after macrocyclic musk scents. Furthermore, they are used for the manufacture of numerous other new 1-substituted or 1-and 2-substituted cyclododecenes and cyclododecanes having good scent characteristics.
