, p. 12770 - 12776 (1998)
Solid-state photoreactions of S-(o-tolyl), S-phenyl, and S-(m-tolyl) 2- benzoylbenzothioates, which formed chiral crystals by spontaneous resolution, underwent an unprecedented intramolecular cyclization involving phenyl migration to afford optically acti
Photochemical transformation of S-aryl 2-benzoylbenzothioates to 3-phenyl-3-arylthiobenzofuranones involving aryl migration

Photochemical reactions of S-aryl 2-benzoylbenzothioates 1 in solution media have been investigated. These thioesters undergo photoinduced cyclization to 3-aryl-3-arylthioisobenzofuranones 2 in yields of 14-46% upon direct irradiation. The photocyclizatio
