Popis

General description

(R)-(−)-Carvone is a monoterpenoid. Its ozonolysis in the gaseous phase has been proposed. Aldehydes (formaldehyde) and biradicals were obtained as the major products. It participates in the diastereoselective synthesis of homochiral octalones.

Application

(R)-(−)-Carvone may be employed as starting reagent for the synthesis of enantiopure (R)-(+)-3-methyl-6-isopropenyl-cyclohept-3-enone-1, a useful intermediate formed during the synthesis of terpenoids. It may be employed as starting reagent for the synthesis of differently protected (4S,6R,7R)-trihydroxy-1-octyne derivatives.

Chiral starting material.
