Abstract
We report an unusual transformation where the transient formation of a nitrene moiety initiates a sequence of steps leading to remote oxidative C-H functionalization (R-CH3 to R-CH2OC(O)R') and the concomitant reduction of the nitrene into an amino group. No external oxidants or reductants are needed for this formal molecular comproportionation. Detected and isolated intermediates and computational analysis suggest that the process occurs with pyrazole ring opening and recyclization.

Abstract
Regioselective C(sp3)-H alkylation of a fructopyranose derivative using electron-deficient alkenes as alkylation reagents was achieved. The reaction proceeded via 1,6-hydrogen atom transfer under photoredox iridium catalysis. Several functional groups were introduced into the fructopyranose derivative.
