Synthesis of N-Boc-(R)-α-phenyl-γ-aminobutyric acid using an in situ diastereoselective protonation strategy
摘要:
The synthesis of (+/-)-N-phthalyl alpha-phenyl-gamma-aminobutyric acid and its asymmetric transformation via ketene formation have been investigated, allowing, after hydrolysis and amine protection, the preparation of the enantiomerically pure N-Boc-(R)-alpha-phenyl-gamma-aminobutyric acid.
