Disclosed are compounds having the structure:
wherein R1a and R1b are independently H, alkyl, F, or fluoroalkyl; wherein R2a, R2b, R2a′, and R2b′ are independently H, alkyl, F, fluoroalkyl, aryl, or alkenyl; wherein R3 is OH, alkoxyl, NH2, alkylamino, or dialkylamino; wherein R4a and R4b are independently H, alkyl, acyl, or alkyloxycarbonyl; wherein R11, R12, R13, R21, R22, and R23 are independently H, alkyl, F, or fluoroalkyl; and wherein C0, C1, C2 and C2′ are independently chiral or achiral. Also disclosed are processes for making a fluorinated β-amino acid comprising the steps of: providing a diol; treating the diol with a thionyl halide with oxidative workup; reacting the product with an azide salt to yield an azido group; oxidizing the product to yield a carboxyl group; and reducing the azido group to yield an amino group.
