What are the synthesis methods of (betaR) -beta- [[ (1,1-dimethylethoxy) carbonyl] amino] -4-fluorophenylpropionic acid?

To prepare (β R ） -β - [[（ 1,1 -dimethylethoxy) carbonyl] amino] -4 -fluorophenylpropionic acid, the method is as follows:

The starting material is selected as a fluorine-containing benzene derivative, and the position of the fluorine atom and the benzene ring in the structure needs to conform to the design of the target product. At the specific position of this benzene derivative, a specific substituent is introduced under suitable reaction conditions to construct a preliminary carbon chain structure.
