Abstract

A series of planar chiral iodoarenes based on [2.2]paracyclophane was synthesized. An efficient asymmetric intramolecular oxidative lactonization of naphthols enabled by a combination of these chiral iodoarenes and mCPBA as oxidant is reported. This reaction proceeds under mild conditions, allowing the formation of spirolactones bearing a tetrasubstituted stereocenter in moderate yields and good enantioselectivity.
