Described for use in augmenting or enhancing the aroma or taste of consumable materials including perfume compositions, colognes and perfumed articles, foodstuffs, chewing gums, toothpastes and medicinal products are the cis and/or trans isomers of the macrocyclic lactone defined according to the structure: ##STR1## produced according to the process of first reacting the ester defined according to the structure: ##STR2## with the alkenol having the structure: ##STR3## in order to produce the di-unsaturated ester having the structure: ##STR4## and then causing the said diester to undergo an internal metathesis to form the compound having the structure: ##STR5##

Use of macrocyclic lactone in augmenting or enhancing aroma or taste of

Described is a class of macrocyclic carbonates defined according to the structure: ##STR1## wherein n is an integer of from 1 up to 8 and m is an integer of from 1 up to 8 and where n and m may be the same or different and organoleptic use thereof in augmenting or enhancing the aroma or taste of foodstuffs, chewing gums, toothpastes, medicinal products, chewing tobaccos, perfume compositions, colognes and perfumed articles (i.e. solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles, cosmetic powders and perfumed polymers).

Perfuming with a macrocyclic carbonate

Described is 2-methoxy-4-(2-methylpropenyl) phenyl ester of isobutyric acid of our invention having the structure: ##STR1## and uses thereof in augmenting or enhancing the aroma or taste of consumable materials including foodstuffs, chewing gums, toothpastes, medicinal products and chewing tobaccos and the process for preparing said 2-methoxy-4-(2-methylpropenyl) phenyl ester of isobutyric acid by reacting isobutyric anhydride with vanillin according to the reaction sequence: ##STR2##

2-Methoxy-4-(2-methylpropenyl) phenyl ester of isobutyric acid, flavor

Described is a class of macrocyclic carbonates defined according to the structure: ##STR1## wherein n is an integer of from 1 up to 8 and m is an integer of from 1 up to 8 and where n and m may be the same or different and organoleptic uses thereof in augmenting or enhancing the aroma or taste of foodstuffs, chewing gums, toothpastes, medicinal products, chewing tobaccos, perfume compositions, colognes and perfumed articles (i.e. solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles, cosmetic powders and perfumed polymers).

Flavoring with a macrocyclic carbonate

Described is di(7-octenyl) carbonate having the structure: ##STR1## and the use thereof as an intermediate in producing the compound having the structure: ##STR2## useful in perfumery.

Di(7-octenyl) carbonate

Described is a class of macrocyclic carbonates defined according to the structure: ##STR1## wherein n is an integer of from 1 up to 8 and m is an integer of from 1 up to 8 and where n and m may be the same or different; processes for producing same by means of first forming dialkenyl carbonates defined according to the structure: ##STR2## by reacting one or both of the alcohols defined according to the structures: ##STR3## with a dialkyl carbonate defined according to the structure: ##STR4## wherein R.sub.1 and R.sub.2 are the same or different C.sub.1 -C.sub.4 lower alkyl; and then carrying out a metathesis reaction on the compound having the structure: ##STR5## thereby forming the compound having the structure: ##STR6## and organoleptic uses of the macrocyclic carbonates having the structure: ##STR7## in augmenting or enhancing the aroma or taste of foodstuffs, chewing gums, toothpastes, medicinal products, chewing tobaccos, perfume compositions, colognes and perfumed articles (i.e. solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles, cosmetic powders and perfumed polymers).

Macrocyclic carbonates and organoleptic uses thereof

Described is 2-methoxy-4-(methylpropenyl) phenyl ester of isobutyric acid having the structure: ##STR1## and uses thereof in augmenting or enhancing the aroma of perfume compositions, perfumed articles and colognes.

2-Methoxy-4-(2-methylpropenyl) phenyl ester of isobutyric acid, and use

Described is a method for augmenting or enhancing the aroma or taste of 'tropical' flavored foodstuffs comprising, adding to said foodstuff, a mixture of:

Flavoring some tropical flavored foodstuffs with mixture of C.sub.4 -C.sub.

Flavoring with macrocyclic lactone

Macrocyclic carbonates, processes for preparing same, organoleptic uses

Described are the alkylthioalkanal dialkyl mercaptals defined according to the generic structure: ##STR1## wherein n is an integer of from 1 up to 3; and wherein R.sub.1 and R.sub.2 are the same or different C.sub.1 -C.sub.3 alkyl; process for preparing same and organoleptic uses thereof in augmenting or enhancing the aroma or taste of foodstuffs, chewing gums, medicinal products and toothpastes.
