An efficient (74% - 97% yield) three-step one-pot synthesis of (R)-Halostachine and analogues from O-protected optically active cyanohydrins is described. The reaction sequence involves a DIBAL reduction of the nitrile to an imine, transimination to a secondary imine and sodium borohydride reduction to the corresponding N-substituted β-ethanolamine. Both O-protected as well as unprotected reaction products can be obtained.
