ABSTRACT:
A process for the manufacture of lavandulol and its esters, starting from the new compound 3,5,5-trimethyl-1,6-heptadien-3-ol, which is converted by conventional methods to 3,5,5-trimethyl-hepta-2,6-dien-1-ol or its esters, which are rearranged to lavandulol or lavandulyl esters by heating at from 150.degree. to 250.degree. C. Using the new process, the desirable product lavandulol, and its esters, which are also of great interest as scents, and even previously unknown lavandulyl esters, can be manufactured simply, in goods yields and in excellent purity, from easily obtainable starting compounds. Both the new starting compound 3,5,5-trimethyl-hepta-1,6-dien-3-ol and the new 3,5,5-trimethyl-hepta-2,6-dien-1-yl esters, obtained as intermediates, are scents and can be employed in the perfumery industry.
