Asymmetric synthesis of (-)-(R)-massoia lactone, (R)-δ-decalactone, and (+)-(3R,5R)-3-hydroxydecano-5-lactone. Formal synthesis of verbalactone

A simple and efficient procedure for the asymmetric synthesis of (-)-(R)-massoia lactone, (R)-delta-decalactone, and (+)-(3R,5R)-3-hydroxy-1,5-decanolide is described. Verbalactone was synthesized using Heck allylation at the key stage of construction of the carbon skeleton.
