SYNTHESIS OF PROTECTED ALLYLIC AMINES FROM ALLYLIC PHENYL SELENIDES: IMPROVED CONDITIONS FOR THE CHLORAMINE T OXIDATION OF ALLYLIC PHENYL SELENIDES

Fankhauser, John E.,Peevey, Richard M.,Hopkins, Paul B.

, p. 15 - 18 (2007/10/02)

Anhydrous chloramine T in methanol is a highly effective reagent for the conversion of allylic phenyl selenides to the corresponding rearranged N-allylic-p-toluenesulfonamides.The reaction presumably proceeds via an allylic selenimide intermediate which undergoes -sigmatropic rearrangement.
