Chiral N-protected α-amino aryl-ketones are one of the useful precursors used in the synthesis of various biologically active compounds and can be constructed via Friedel-Crafts acylation of N-protected α-amino acids. One of the drawbacks of this reaction

Chiral N-(trifluoroacetyl)-α-amino acid chlorides unergo Friedel-Crafts reaction with benzene and 1,2-dimethoxybenzene under mild conditions commonly with complete (>99percent) preservation of configurational identity.The resultant (trifluoroacetyl)amino ketones may be deoxygenated with Et3SiH or H2/Pd-C in acidic media to the corresponding N-(trifluoroacetyl)-β-arylalkylamines likewise without loss of configurational purity.
