Described for use in augmenting or enhancing the aroma or taste of smoking tobaccos and smoking tobacco articles, e.g., the body of smoking tobacco, the wrapper or the filter therefor in a cigarette or cigar, or the whole cigarette or cigar itself are compounds defined according to the generic structure: ##STR1## wherein R.sub.1 represents hydrogen, methyl or acetyl and wherein R.sub.2, R.sub.3, R.sub.4 and R.sub.5 represent the same or different hydrogen, methyl or ethyl.

Process for augmenting or enhancing the aroma or taste of smoking

Described are organoleptic compounds having the generic structure: ##STR1## wherein R.sub.1 represents hydrogen, methyl or acetyl and wherein R.sub.2, R.sub.3, R.sub.4 and R.sub.5 represent the same or different hydrogen, methyl or ethyl.

Tricyclic alcohols, ethers and esters, process for preparing same and

Described is a process for preparing at least one secondary alcohol of the class of methyl substituted pinyl hydroxy pentenes comprising the step of:

Methyl substituted pinyl oxopentenes, organoleptic uses thereof and

Described are methyl substituted pinyl oxopentenes and mixtures of same defined according to the structure: ##STR1## wherein Z represents methylidene pinyl oxopentenes and mixtures of same defined according to the structure: ##STR2## ethylidene defined according to the structure: ##STR3## or ethylenyl defined according to the structure: ##STR4## wherein one of the dashed lines represents a carbon-carbon single bond and the other of the dashed lines represents no bond; wherein n is 0 or 1 and m is 0 or 1 with the sum of n+m being equal to 1; wherein X represents carbinol having the structure: ##STR5## or ketone having the structure: ##STR6## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen or methyl.

Methyl substituted pinyl oxopentenes and organoleptic uses thereof

Described are tertiary pentamethylindanol derivatives defined according to the structure: ##STR1## wherein the dashed line represents a carbon-carbon single bond or a carbon-carbon double bond and uses thereof in augmenting or enhancing the aroma or taste of consumable materials selected from the group consisting of perfume compositions, colognes, perfumed articles, foodstuffs, smoking tobaccos and smoking tobacco compositions.

Tertiary pentamethylindanol derivatives and organoleptic uses thereof

Described are tertiary pentamethylindanol derivatives defined according to the structure: ##STR1## wherein the dashed line represents a carbon-carbon single or a carbon-carbon double bond and uses thereof in augmenting or enhancing the aroma or taste of smoking tobaccos or smoking tobacco compositions.

Use of pentamethylindanol derivatives in augmenting or enhancing the

Described are methyl substituted pinyl oxopentenes and mixtures of same and uses thereof in augmenting or enhancing the aroma or taste of consumable materials including foodstuffs, chewing gums, toothpastes, medicinal products, chewing tobaccos, perfume compositions, perfumed articles (including perfumed polymers, solid or liquid cationic, anionic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles, optical brightener compositions, and cosmetic powders), colognes, smoking tobacco compositions and smoking tobacco articles including cigars, cigarettes and integrated and separate filters therefor. Also described are processes for preparing such compounds including the steps of reacting alpha and/or beta pinene with carbon monoxide and hydrogen via an oxo reaction in the presence of a catalyst to produce a mixture of aldehydes and then reacting the resulting mixture of aldehydes with methyl ethyl ketone in the presence of a basic catalyst to produce the compounds of our invention.

Flavoring with tertiary pentamethylindanol derivatives

Described is a process for preparing solanone and norsolanadione wherein in preparing solanone, the compound having the structure: ##STR1## or a mixture of compounds defined according to the structure: ##STR2## is reacted with methyl lithium and the resulting intermediate is hydrolyzed and the resulting compound is dehydrated and wherein in preparing norsolanadione this compound or mixture of compounds is reacted with ethylene glycol or propylene glycol thereby forming a ketal and the resulting ketal is reacted with methyl lithium and the resulting intermediate is then hydrolyzed in the presence of acid in which one of the dashed lines represents a carbon-carbon single bond and the other of the dashed lines represents a carbon-carbon double bond.

Process for producing solanone, norsolanadione and intermediates therefor

Described are methyl substituted pinyl oxopentenes and mixtures of same defined according to the structure: ##STR1## having utility in augmenting or enhancing the aroma or taste of consumable material.

Organoleptic use of methyl substituted pinyl oxopentenes

Use in augmenting or enhancing the aroma or taste of foodstuffs or

Described is a process for preparing solanone and norsolanadione, both useful as tobacco flavorants.

Described is a mixture of vinyl alkanols produced by carrying out an oxo reaction on pinene and then carrying out an oldol condensation with the reaction product. The resulting products are useful as favoring and perfumery.

Described are hydroxy alkenyl bicyclic terpene derivatives useful in perfumery.
