The present invention provides a production method of an allylic amine represented by the formula (III):
wherein R
3
is as defined in the specification,
which comprises reacting by an allylic alcohol represented by the formula (II):
wherein R
3
is as defined in the specification,
with sulfamic acid, in the presence of a phosphoramidite ligand represented by the formula (I):
wherein each symbol is as defined in the specification, and an iridium complex. According to the present invention, a primary allylic amine can be produced directly from an allylic alcohol, without use of an activator for an allylic alcohol and conversion of an allylic alcohol into an activated compound thereof.

rearrangement of (E)-allylic trichloroacetimidates to provide transposed allylic trichloroacetamides of high enantiopurity, a transformation that underlies the first truly practical method for transforming prochiral allylicalcohols to enantioenriched allylic amines and congeners. The high functional group compatibility of this asymmetric rearrangement and the demonstrated broad utility in synthesis of the allylic
