Methyl substituted oxobicyclo-4,4,0-decane derivatives, process for preparing same and organoleptic uses thereof

摘要

Described are compounds having the generic structure: ##STR1## wherein the dashed line represents a carbon-carbon single bond or a carbon-carbon double bond; wherein X represents the moieties: ##STR2## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen or methyl with the proviso that (i) at least three of R.sub.1, R.sub.2, R. sub.3 and R.sub.4 represent hydrogen and (ii) when the dashed line is a carbon-carbon single bond and X is: ##STR3## then one of R.sub.1, R.sub.2, R.sub.3 or R. sub.4 is methyl and the other represents hydrogen; wherein R.sub.5 represents hydrogen, MgX, MgR.sub.7, CdR.sub.7, ZnR.sub.7, Na, K or Li; wherein X represents Chloro, Bromo or Iodo; wherein R.sub.6 represents hydrogren or methyl; and wherein R.sub.7 represents lower alkyl; and uses thereof for their organoleptic properties in augmenting or enhancing or enhancing the aromas or tastes of perfumes, perfumed articles, foodstuffs, chewing gums, smoking tobaccos, toothpastes, medicinal products, chewing tobacco and smoking tobacco articles, as well as processes for preparing same.
