Electrochemical Imination of Sulfoxides Using N-Aminophthalimide
摘要:
[GRAPHICS]A novel electrochemical sulfoxide imination process is described. Our approach starts with a highly selective nitrene transfer from N-aminophthalimide to a variety of sulfoxides. This oxidative treatment is followed by reductive N-N bond cleavage under the controlled current conditions, which leads to a range of parent NH sulfoximines. In addition to solving the challenging problem of removing the N-phthalimido group, the overall process avoids the use of toxic oxidants and metal additives.

ABSTRACT Herein we utilized, for the first time, 2-iodoxybenzoate along with scandium triflate as a specific oxidant for PhthNH2 to create sulfoximines. This method efficiently effects imination of aryl, benzyl, cyclic and alkyl substituted S˭O bonds with good to excellent yields. In addition, sterically encumbered sulfoxides have been studied and found that the present protocol is the worthy choice
