Direct Synthesis of Enolizable N-Sulfonyl Ketimines under Microwave Irradiation

N-sulfonyl imines are widely used as substrates for a range of transformations. Access to N-sulfonyl aldimines is straightforward through direct condensation between the parent aldehyde and the sulfonamide. However, this approach is not efficient for the synthesis of enolizable N-sulfonyl ketimines. Herein we report a rapid and facile methodology for obtaining these products using microwave irradiation.
