and efficient synthesis for the construction of the complex non-anomeric spiro-fused bicyclic sugar derivatives from glycosyl 6-trichloroacetimidates under visible light conditions was developed. The overall reaction proceeds via in situ generation of imidate nitrogen-centered radicals followed by 1,5-hydrogen atom transfer to form the intramolecular carbon-nitrogen (C−N) bond.
