Probing Unspecific Peroxygenases for Non‐Natural Nitrene Chemistry

Unspecific peroxygenases (UPOs) are shown to perform nitrene chemistry, utilizing the inexpensive commodity chemical hydroxylamine as cosubstrate. 1,2,3,4-tetrahydronaphthalene is investigated as model substrate using a diverse panel of UPOs, reaching turnover numbers up to 745 and enantiomeric excess values up to 62%. Overall, the first account of UPO activity regarding non-natural nitrene transfer reactivities is reported.
