Bicyclic lactones, perfumery uses thereof, processes for preparing same and intermediates therefor

Abstract

Described are bicyclic lactones, both fused ring lactones defined according to the generic structure: and spiro lactones defined according to the generic structure: uses thereof in augmenting, enhancing or imparting aromas in or to perfume compositions, perfumed articles, colognes and perfumed polymers; processes for preparing such bicyclic lactones and intermediates therefor.

1 . A process for augmenting, enhancing or imparting an aroma in or to a consumable material selected from the group consisting of perfume compositions, perfumed articles, colognes and perfume polymers, comprising the step of intimately admixing with a consumable material base an aroma augmenting, enhancing or imparting quantity and concentration of bicyclic lactone fragrance compound having the following structure:  
     
       
         
         
             
             
         
       
     
     wherein Z is a moiety selected from the group consisting of:  
     
       
         
         
             
             
         
       
     
     and wherein one of R 1  or R 3  is methyl and the other is hydrogen; wherein R 4 , R 5 , R 6 , R 7  and R 8  and R 9  are hydrogen or nonadjacent C 1 -C 3  alkyl.  
   
   
       2 . The process of  claim 1  wherein the bicyclic lactone has a structure selected from the group consisting of:  
     
       
         
         
             
             
         
       
     
   
   
       3 . (canceled)  
   
   
       4 . A perfumed article comprising a perfumed article base and an aroma augmenting, enhancing or imparting quantity and concentration of a bicyclic lactone having the following structure:  
     
       
         
         
             
             
         
       
     
     wherein Z is a moiety selected from the group consisting of:  
     
       
         
         
             
             
         
       
     
     and wherein one of R 1  or R 3  is methyl and the other is hydrogen; wherein R 4 , R 5 , R 6 , R 7 , R 8  and R 9  are hydrogen or nonadjacent C 1 -C 3  alkyl.  
   
   
       5 . (canceled)  
   
   
       6 . A perfume composition comprising a perfume base and intimately admixed therewith an aroma augmenting, enhancing or imparting quantity of a bicyclic lactone having the following structure:  
     
       
         
         
             
             
         
       
     
     wherein Z is a moiety selected from the group consisting of:  
     
       
         
         
             
             
         
       
     
     and wherein one of R 1  or R 3  is methyl and the other is hydrogen; wherein R 4 , R 5 , R 6 , R 7 , R 8  and R 9  are hydrogen or nonadjacent C 1 -C 3  alkyl.  
   
   
       7 . The process of  claim 1  wherein the consumable material is a detergent composition or a fabric softener composition.  
   
   
       8 . The process of  claim 2  wherein the consumable material is a detergent composition or a fabric softener composition.  
   
   
       10 . A bicyclic lactone fragrance compound having a structure selected from the group consisting of:
