The C-oxyalkylation of N-aryl-alpha-amino acids by hexafluoroacetone (1) and methyl trifluoropyruvate (2), followed by acylation of the products 3-13, 15, and 17 formed, was carried out. The activity of the synthesized anilides against pathogens of plant fungus diseases was studied.

Highly Enantioselective Insertion of Carbenoids into N−H Bonds Catalyzed by Copper Complexes of Chiral Spiro Bisoxazolines
A highly efficient copper-catalyzed asymmetric insertion of α-diazoesters into N−H bonds has been realized by using chiral spiro bisoxazoline ligands, affording α-amino acid derivatives in high yields with excellent enantioselectivities.

aromatization‐blocked strategy, the 1,2‐dihydroquinoline skeleton was efficiently constructed by sp3 CH bond oxidation of N‐arylalaninates under catalytic radical cation salt‐promoted conditions. Investigation of the reaction scope shows broad generality and good functional group tolerance. This method provides a new way to synthesize 1,2‐dihydroquinoline derivatives from easily accessible starting materials
