A photochemical protocol using blue light allows the N–H insertion of amides, isatins, sulfonamides and imides into aryldiazoacetates to afford the corresponding α-amino esters. This method is experimentally simple, inexpensive and tolerates numerous functional groups, thus allowing the straightforward preparation of a variety of α-aryl amino acid derivatives in good yields.
Novel formation and crystal structure of 2-(2,2,2-trifluoroethylidene)-6-trifluoro-methyl-2,3-dihydro-4H-1,4-oxazin-3- ones from N-acetyl-N-alkyl-α-amino acids

The title compounds (2a-g) were formed from N-acetyl-N-alkyl-α-amino acids (1a-g) on treatment with trifluoroacetic anhydride in the presence of pyridine. The structure of the product (2a) was determined by single crystal X-Ray analysis.
