Abstract
The invention relates to new methylcyclododecatri-2,5,9-en-1-oles of formula ##STR1## in which one of the dashed lines represents a double bond and the other a single bond, and the endocyclic double bonds may be cis- and trans-configured, a process for their preparation and their use as scents.
Claims3
A methylcyclododecatri-2,5,9-en-1-ol of the formula ##STR3## in which one of the dashed lines is a double bond and the other is a single bond.
A process for the preparation of methylcyclododecatri-2,5,9-en-1-oles of the formula ##STR4## wherein one of the dashed lines is a double bond and the other is a single bond,
- which process comprises:
- (a) monoepoxydising 1,5,10-trimethyl-cyclododeca-tri-1,5,9-ene with a peracid and
- (b) isomerising the monoepoxide obtained, 1,6,9-trimethyl-1,2-epoxycyclododeca-5,9-diene, by heating in the presence of aluminum ispropylate.
