Yes, nitrenes did “N,O”! Intermolecular addition of nitrene to enecarbamates and enesulfonamides gives oxyamidated products in excellent yields of up to 98 % and with good levels of stereoselectivity. Complete regioselectivity is also observed, leading to the formation of N,O‐acetals which can further react with various nucleophiles under acidic conditions (see scheme; TcesNH2=trichloroethylsulfamate)
