摘要:
Derivative compounds of 1,5-dimethylbicyclo [3,2,1] octane of the general formula ##STR1## and perfume compositions containing these derivatives, wherein X represents a C.dbd.O group, a ##STR2## group or a ##STR3## group, in which R.sub.1 and R.sub.2 are alkyl groups and R.sub.3 is an ethylene or trimethylene group which may be substituted with one or more alkyl groups. These derivative compounds may be prepared by oxidation of 1,5-dimethylbicyclo [3,2,1] octan-8-ol or an ester thereof optionally followed by reaction with an alkanol or a 1,2- or 1,3-alkane-diol.

Provided are compounds that are capable of modulating the activity of the influenza A virus via interaction with the M2 transmembrane protein. Also provided are methods for treating an influenza A-affected disease state or infection comprising administering a composition comprising one or more compounds that have been identified as being capable of interaction with the M2 protein.
摘要:
The present invention relates to a novel thermo-isomerization method for rapidly and simply producing macrocyclic ketones of the formula Ia or Ib. The macrocyclic ketones are prepared in the gas phase at temperatures above 500° C. rapidly and in a simple manner from alcohols of the formula IIa and IIb directly with a high yield. In the formulae Ia, Ib, IIa and IIb, R1-R5, and n have the meanings given in the description.
摘要:
Novel odorant and/or flavoring substances are described. These are the compounds of the formula ##STR1## wherein: R.sup.1 represents methyl or ethyl,R.sup.2 represents hydrogen or methyl,the dotted line represents an optional carbon-carbon bond,n is 0 or 1, and,when n is O, R.sup.3 is hydrogen and R.sup.4 represents acetyl or propronyl, and,when n is 1, R.sup.3 represents methyl or ethyl and R.sup.4 represents hydrogen or methyl,with the exception of 1,4,4,7a-tetramethyl-3a,4,5,7a-tetrahydro-7(6H)-ind-1-enone.The compounds of formula I possess organoleptic properties which make them particularly suitable for use as odorant and/or flavoring substances.
摘要:
The present invention relates to substituted spirocyclic derivatives having the general formula: ##STR1## wherein the dotted line represents a carbon-carbon double bond or a carbon-carbon single bond, wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, and R.sub.6 are each the same or different, hydrogen or lower alkyl, wherein Z is one of the following: ##STR2## wherein R.sub.7 is either hydrogen or lower alkyl, wherein R.sub.8 and R.sub.9 are each lower alkyl; their methods of preparation and their use as odor-modifying ingredients in perfumes and perfumed products, and as flavor-modifying ingredients in the flavoring of foodstuffs and tobacco products.

Perfume compositions, perfumed materials and perfumed articles containing derivatives of spiro [5.5] undecane-3-one and/or undecene-3-one having the following formula ##STR1## wherein R.sub.1 and R.sub.2 are hydrogen or methyl and the dotted line is a single or double bond with the proviso that when this dotted line is a double bond R.sub.1 and R.sub.2 are both hydrogen.The use of one or more derivatives of spiro [5.5] undecane-3-one and/or -undecene-3-one having formula 1 as a perfume component in perfume compositions and in imparting fragrance to materials and articles for example soaps, cleaning preparations and cosmetic preparations.
摘要:
A novel process for producing 3-formylcyclopentanone derivatives which are useful intermediates for syntheses of five-membered ring compounds such as prostaglandins is disclosed. In the process, 3-formylcyclopentanone derivatives are produced starting from .beta.-dicarbonyl compounds and azides through several-step reactions.
