Abstract
Mixtures of new dimethyl-tricyclo[5.2.1.0.sup.2,6 ]decane derivatives, notably the primary isomers of the common formula A, wherein R.sup.1 and R.sup.2 mean either methyl group or hydrogen, one of the substituents being a methyl group and the other hydrogen, R.sup.3 and R.sup.4 mean either methyl group or hydrogen, one of the substituents being a methyl group and the other hydrogen, and X indicates the .pi.-system of a C-C double bond or an epoxide system, can advantageously be used as new acent- and flavor materials. The compounds of the common formula A, were prepared by hydrogenation of dimeric methylcyclopentadiene selectively in the norbornane part and when desired by epoxidation of the remaining double bond. ##STR1##
