catalytic site-selective installation of a photoredox active carboxylic ester group to a specific hydroxyl unit of an unprotected sugar. The second step, namely, “editing”, features a C–O bondcleavage to form a carbon radical intermediate that undergoes further transformations such as C–H and C–C bond formations. Our strategy constitutes the most effective and shortest route in direct transformation and modification
