A New Route to (+)-2,3-(Isopropylidenedioxy)-4-cyclopentenone via the Optically Active Dicyclopentadiene Intermediate

Abstract
Chiral synthesis of the dicyclopentadiene derivative and its stereoselective conversion into (+)-2,3-(isopropylidenedioxy)-4-cyclopentenone, a versatile building block for the synthesis of cyclopentanoid natural products, have been described.
