yields and shows complete enantioselectivity in the formation of the (S)-(+) isomers. Enantiopure 6a–c are versatile chiral building blocks for the synthesis of bisabolane sesquiterpenes. Their usefulness is shown in the preparation of (S)-(+)-curcuphenol, (S)-(+)-xanthorrhizol, (S)-(−)-curcuquinone and (S)-(+)-curcuhydroquinone.
