Abstract

Abstract WHEREIN EACH OF R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 is selected from the group consisting of hydrogen and methyl; wherein the dashed line is a carbon-carbon single bond or a carbon-carbon double bond; wherein R1 is limited to hydrogen when (i) the dashed line is a carbon-carbon single bond; (ii) R2, R3, R4, R6, R7, R8, R9 and R10 is hydrogen and (iii) R5 is hydrogen or methyl and wherein when the dashed line is a carbon-carbon single bond, one of R3 or R4 is hydrogen; and processes for preparing the above-mentioned compounds and in addition compounds having similar structures, that is, when the dashed line is either a carbon-carbon single bond or a carbon-carbon double bond; R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 are each the same or different and each represents hydrogen and wherein when R3 or R4 is hydrogen the dashed line represents a carbon-carbon single bond and when R3 and R4 are both methyl, the dashed line represents a carbon-carbon double bond, involving first intimately admixing a methyl substituted cyclohexadienone having the structure: The ketone may either be immediately cyclized using an alkali metal such as sodium, potassium or lithium in the case of X being halogen, or when X is OH, the ketone is first halogenated with a halogenating agent to first form a compound having the structure: WHEREIN X can be either hydroxyl, bromo or chloro thereby forming a diene compound having the structure: AND THEN HYDROGENATING THE DIENE COMPOUND WITH HYDROGEN IN THE PRESENCE OF A HYDROGENATION CATALYST THEREBY PRODUCING A KETONE HAVING THE STRUCTURE: WHEREIN Y is bromo or chloro and subsequently the halogenated compound may then be cyclized using a cyclizing agent. D R A W I N G WITH AN ACETYLENIC COMPOUND HAVING THE STRUCTURE: D R A W I N G Processes and compositions for altering the flavor and/or aroma of consumable products including foods, tobacco and perfumes utilizing as the essential ingredient at least one organic tricyclic alcohol having the formula:
