应用

(2R,3S)-(-)-N-Boc-6-oxo-2,3-diphenylmorpholine (Williams′ morpholinone) can be used as a reactant to prepare:
  • Indole substituted tryptophan derivatives by alkylation with quaternary gramine in the presence of a base.
  • Tyrosine derivatives, which can be utilized as building blocks for the total synthesis of ecteinascidin and safracin family of alkaloids.
