3,6-Dimethyl-3-hydroxy-oct-1-ynes and -oct-1-enes, derivatives of these, and their use as scents, and in the preparation of 3,6-dimethyl-3- hydroxy- octane
3,6-Dimethyl-3-hydroxy-oct-1-ynes and -oct-1-enes and their esters with lower alkanoic acids, of the general formula I ##STR1## where X and Y are H or the two X's and/or the two Y's together are a further bond between the carbon atoms on which they are present, and R is H, --CO- -CH. sub.3, --CO--C. sub.2 H.sub.5 or --CO--C.sub.3 H.sub.7, their use as scents, and a process for the preparation of 3,6-dimethyl-3-hydroxy- octane. The novel compounds exhibit interesting, predominantly floral, woody, herbal and fruity notes. The alcohols of the formula I are of particular importance because they serve as intermediates for a novel and particularly advantageous method of obtaining 3,6-dimethyl-3-hydroxy- octane, a compound required in large amounts as a fragrance for soaps and detergents.
