Abstract

Photoinduced Electron Transfer Oxygenations of 4-Arylmethylene-1,3(2H,4H)-isoquinolinediones afforded oxiranes (5a-5c, 6a-6c, 7) and 1, 3, 4-isoquinolinetriones (8 and 9) as major products in high yields in the presence of triethylamine (TEA). These oxygenation reactions are initiated by single electron transfer between photoexcited 4-Arylmethylene-1,3(2H,4H)-isoquinolinediones and TEA, and proceeded via the anion radicals of the substrates.
