Abstract: An optically active spirolactone compound is highly enantioselectively produced by using an iodoarene derivative which can be synthesized easily and which is not racemized easily. A hypervalent iodine compound precursor (iodoarene derivative) which was able to be designed flexibly was synthesized from 2,6-dihydroxyiodoarene by using 1,2-aminoalcohol as a chiral source in short steps, a hypervalent iodine compound was prepared in a reaction system (in situ) by using a catalyst quantity of the resulting precursor in the presence of a stoichiometric quantity of m-CPBA, and a spirolactonization reaction of 3-(1-hydroxy-2-naphthyl)propionic acid was induced. As a result, a corresponding spirolactone compound was obtained at a high enantiomeric excess.
