Abstract
The invention provides a method for converting a lactone of a diamondoid compound to the hydroxyketone of the diamondoid compound wherein the hydroxyl group and the carbonyl group are separated by at least one bridgehead carbon comprising reacting an anhydride containing from about 2 to about 20 carbon atoms with the lactone of the diamondoid compound in the presence of acid.
Claims14
A method for converting a lactone of a diamondoid compound to the hydroxyketone of the diamondoid compound wherein the hydroxyl group and the carbonyl group are separated by at least one bridgehead carbon comprising reacting an anhydride containing from about 2 to about 20 carbon atoms with the lactone of the diamondoid compound in the presence of acid and then hydrolyzing the intermediate keto-esters.
A method for converting 4-oxahomoadamantan-5-one to 4-acetoxyadamantanone comprising reaching acetic anhydride with 4-oxahomoadamantan-5-one in the presence of acid at temperature above ambient.
A method for converting a lactone of a diamondoid compound to the hydroxyketone of the diamondoid compound wherein the hydroxyl group and the carbonyl group are separated by at least one bridgehead carbon comprising reacting a metal azide with the lactone of the diamondoid compound in the presence of acid.
