A mild and highly efficient access to N-sulfonyl imines through the oxidation of corresponding N-tert-butylsulfinyl imines and N-p-tosyl-sulfinyl imines with UHP in the presence of catalytic amount MTO was developed. Under mild reaction conditions, this highly selective reaction, provides a general and efficient access to N-sulfonyl aldimines, ketimines and α-ketiminoesters in excellent yield. The
