SulfonesQ 0600 Regioselectivity Control of Radiation-Induced Reaction: Electron Beam-Induced

Fries Rearrangement of Sulfonamide within a β-Cyclodextrin Inclusion Complex. — Electron beam irradiation of sulfonamides (I) and (IV) within a β-cyclodextrin in-clusion complex in the solid state induces the Fries-rearrangement, which proceeds at a shorter reaction time and with reversed stereoselectivity compared with that of the neat sulfonamide crystals. — (KATO*, J.; KAKEHATA, H.; MAEKAWA, Y.; YAMASHITA, T.; Chem.
