WebSpecifically, we report a strategy for biocatalytic phenolic cross-coupling through oxidative C–C bond formation. Using cytochrome P450 enzymes, we demonstrate the ability to catalyze cross-coupling reactions on a panel of phenolic substrates and further demonstrate the ability to tune these catalysts to WebApr 12, 2024 · The formation of ether bonds belongs to coupling reaction between phenoxy radical and benzoyl carbon radical. The IR spectra of tryptophan and corresponding oxidative product are shown in Figure 3b. The peaks in the range of 3200–3425 cm −1 are assigned to ν(N-H) of tryptophan.
