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
Abstract 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 3 , --CO--C 2 H 5 or --CO--C 3 H 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.
3,6-Dimethyl-3-hydroxy-oct-1-ene and its derivatives, of the general formula I ##STR7## 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 3 , --CO--C 2 H 5 or --CO--C 3 H 7 .
