The invention concerns a process for the manufacture of a mixture of (3aα,5aβ,9aα,9bβ)-dodecahydro-3a,6,6,9a-tetramethylnaphtho-[2,1-b]furan and (3aα,5aβ,9aα,9bα)-dodecahydro-3a,6,6,9a-tetramethylnaphtho[2,1-b]furan which utilizes the substituted hexenoic acids, 6-(2',6',6'-trimethyl-cyclohex-1'-en-1'-yl)-4-methyl-hex-2- or -3-enoic acid. The invention also concerns nitriles and a process for manufacture of the hexonic acids from the nitriles, having the formula STR1 wherein one of the bonds denotes a single bond and the other denotes a double bond, and, R represents hydrogen or the ester group COOR1 in which R1 represents a lower alkyl or aryl group.
