Effective Synthesis of Optically Active Trifluoromethyldiazirinyl Homophenylalanine and Aroylalanine Derivatives with the Friedel-Crafts Reaction in Triflic Acid
The Friedel-Craftsreaction with 3-(3-methoxyphenyl)-3-(trifluoromethyl)-3H-diazirine and opticallyactive N-TFA-Asp(Cl)-OMe in triflic acid afforded homophenylalanine derivatives without any loss of the optical purity.
