Very recently, we reported the isolation of new iodonium salts formed by the spirocyclization, in which the possibility of a similar one-pot synthesis was described for specific cases. The utilization and optimization of the in situ generated hypervalent iodine species from iodoarenes were not treated in that study. See

Other regioisomeric bis(iodoarene)s of 3h were less effective than the 2,2′-derivative in this transformation The fluoroalcohols can accelerate generation of hypervalent iodine(iii) species from iodoarenes and formation of the diaryliodonium salts. See

The use of excess amounts of the nucleophiles (∼5 equiv.) was possible in order to avoid introduction of mCPBA to the final spirocyclic products, though it was a very minor competitive path For selected examples of natural product syntheses containing the related ortho-spirolactone structures, see
