Described for the use in foodstuff, chewing gum, toothpaste and medicinal product flavor and aroma, tobacco flavor and aroma and perfume aroma augmenting, modifying, enhancing and imparting compositions and as foodstuff, chewing gum, toothpaste, medicinal product, tobacco, perfume and perfumed article aroma imparting materials are one or more alkenyl or alkylidene norbornyl ketone derivatives having the generic structure: ##STR1## wherein R is C.sub.3 -C.sub.5 alkenyl or C.sub.3 -C.sub.5 alkylidene and the dashed lie is a carbon-carbon single bond or a carbon-carbon double bond, specifically the compounds having the structures: ##STR2## and products produced according to the process of reacting 2-acetyl-3,3-dimethyl-5-norbornene with a complex of N-methylaniline and an alkyl magnesium halide to form a grinard salt of 2-acetyl-3,3-dimethyl-5-norbornene having the structure: ##STR3## said reacting being carried out from -5.degree. C. up to about 40.degree. C.; reacting the resulting compound with acid aldehyde in the presence of a solvent selected from the group consisting of benzene, tetrahydrofuran, and diethyl ether at a temperature in the range of from -5.degree. C. up to 20.degree. C.; hydrolyzing the resulting material to form substantially a keto alcohol in the presence of a mineral acid; and then dehydrating the resulting keto alcohol with a mild dehydrating agent at a temperature in the range of from 80.degree. C. up to 150.degree. C. over a period of time of from 1 up to 5 hours in the presence of a strong acid.

Processes and compositions are described for the use in foodstuff, chewing gum, toothpaste and medicinal product flavor and aroma and perfume aroma augmenting, enhancing, modifying and imparting compositions and as foodstuff, chewing gum, toothpaste, medicinal product, perfume and perfumed article aroma imparting materials of 3,3-dimethyl-2(3-butenyl) norbornanol-2 (hereinafter referred to as the "norbornanol derivative" having the structure: ##STR1## (which structure is intended to cover both the "endo" and the "exo" isomers thereof) produced by a process which comprises reacting an allylic Grignard reagent having the structure: wherein X is chloro, bromo or iodo with camphene oxide having the structure: ##STR2## by either "exo" camphene oxide or "endo" camphene oxide or a mixture of "exo" and "endo" camphene oxide. Addition of the said norbornanol derivative to consumable materials is indicated to produce:(a) In foodstuffs, foodstuff flavorings, chewing gums, toothpastes and medicinal products, sweet, fruity, berry-like aromas with woody, incense-like, cedarwood-like, tea-like and floral nuances and incense-like and cedarwood-like flavors with rosey, berry and tea-like nuances; and(b) In perfumes, colognes and perfumed articles, sweet, woody, thujone-like aromas with strong fir-balsam, armoise, cedarleaf, piney, earthy and camphoraceous nuances.

摘要:
The present invention relates to diterpene compounds of general formula (I) capable of contrasting the antibiotic-resistance mediated by the ArnT enzyme, to their use as a medicament, in particular for use as an adjuvant of an antibiotic therapy in the treatment of antibiotic-resistant bacterial infections. The invention relates also to associations of one or more of the compounds of formula (I) with at least another active ingredient, in particular an antibacterial agent and/or an antibiotic, and compositions comprising one or more compounds of formula (I) or the association according to the present invention and at least one pharmaceutically acceptable excipient and/or carrier as well as to products, in particular medical devices, comprising at least a compound, an association or a composition according to the present invention. Moreover, the invention relates to the use of compounds of formula (I) to sensitize a bacterium to an antibacterial agent or an antibiotic, for example, colistin (polymyxin E) or polymyxin B and to an in vivo or in vitro method for sensitizing a bacterium to an antibacterial agent or an antibiotic comprising the exposure of said bacterium to one or more compounds of formula (I) together with colistin.
