In particular, the invention discloses asymmetric synthesis of chiral phthalides via synergetic nitrile accelerated oxidative cyclization of o-cyano substituted aryl alkenes in high yield and enantiomeric excess (ee) in short reaction time. Also, disclosed herein is “one-potâ€? asymmetric synthesis of biologically important natural compounds having 3-substituted chiral phthalide structural framework in the molecule.
