Synthesis of 11-aminodrim-7-ene from drimenol

11-Aminodrim-7-ene was synthesized from drimenol in four steps. Drimenol was oxidized into drimenal and its oxime was dehydrated by p-tosylchloride or acetic anhydride in pyridine to form 9-cyano-11-nordrim-7-ene, reduction of which by LiAlH₄ in the presence of anhydrous AlCl₃ produced 11-aminodrim-7-ene. The reaction of 9-cyano-11-nordrim-7-ene, NaBH₄, and CoCl₂·6H₂O produced a mixture of drimenylamine and 7,8-dihydrodrimenylamine in a 2:1 ratio.
