Fluorinated amino acids Part 2: Synthesis of diastereomeric N-acyloxazolidinone precursors
摘要:
Evans' chiral auxiliary is used to resolve 3-difluoromethyl-3-(3-benzyloxyphenyl)propionic acid (8), which provides key building blocks for the synthesis of chiral beta-substituted m-tyrosine derivatives.
