Readily synthesized bench-stable glycosyl dithioimidocarbonates are useful -glycoside precursors. Under mild photochemical conditions, these glycosides undergo desulfurative glycosyl radical generation in the presence of weak acid, 4CzIPN, and Hantzsch ester. These radicals perform well in Geise-like reactions to yield -glycosides with high stereoselectivity.
