Manipulation of Substrate-Controlled Diastereoselectivities in Hydroborations in Acyclic Allylamine Derivatives
Racemic, and optically active, 2-methyl-3-(N-tosylamino)alkenes I were prepared and subjected to both catalyzed and uncatalyzed hydroborations.Data obtained for the catalyzed hydroborations of these allylamine derivatives are consistent with the theory of

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