Procedure

Prod.: (many methods) e.g. from Myrcene, via Myrcene dihydrochloride to Dichloro di-methyloctene. This is converted to Chloro di-hydrogeranyl acetate (andneryl acetate) with Sodium Acetate in Benzene in presence of Triethylamine. The acetates are saponified with Calcium hydroxide to yield Hydroxycitronellol, from which the aldehyde is prepared by oxidation.
