A potential pharmacologically active chiral 3-substituted 4-hydroxy-2-oxo-2H-chromene skeleton has been synthesized by enantioselectiveMichael addition catalyzed by PYBOX-DIPH-Zn(OTf)2 complex. The methodology has successfully been employed in the synthesis of (R)-Warfarin and another related compounds.
