Abstract
R-Carvone on heating with Pb(OAc)4 in benzene gives (2RS)-2-hydroxy-2-[(1S)-4-methyl-5-oxocyclohex-3-en-1-yl)]-prop-1-yl bis(acetoxy)acetate. Alkaline hydrolysis of this compound affords the corresponding diol which under acidic catalysis is transformed into bis-hydroxy ether and 1,4-dioxane derivatives.
