The O-allylic substitution of hydroxylamines having an N-electron-withdrawing substituent proceeded smoothly to afford O-allylated products by using [IrCl(cod)]2 or Pd(PPh3)4.
hydroxylamines was observed in iridium-catalyzedreaction. Regio- and enantioselectiveallylic substitution of the unsymmetrical phosphates with hydroxylamines was studied by using the iridium complex of chiral pybox ligand. The aqueous-medium reaction with hydroxylamines proceeded smoothly in the presence of Ba(OH)2·H2O to give the branched products with good enantioselectivities.
