| 摘要 |
Described are 1-hydroxymethyl-2-acyl cyclopropane derivatives defined according to the structure: <IMAGE> wherein Z represents hydrogen, acyl having the structure: <IMAGE> and substituted oxyacyl having the structure: <IMAGE> and cyclic condensation products thereof having the structure: <IMAGE> wherein R1, R2 and R3 represent C1-C10 alkyl; wherein R1' represents C1-C10 alkylidene and wherein R4, R5, R6 and R7 represent hydrogen or C1-C3 lower alkyl; processes for preparing same by means of a reaction of a halomethyloxirane or substituted halomethyloxirane with a substituted 1,3-propanedione derivative; and organoleptic uses of such 1-hydroxymethyl-2-acyl cyclopropane derivatives in augmenting or enhancing the aroma or taste of perfume compositions, perfumed articles (e.g. solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles, perfumed polymers, hair preparations and shampoos), colognes, foodstuffs, chewing gums, toothpastes, medicinal products and chewing tobaccos.
