Cyclic imines bearing CF 3 and C 2 F 5 group were successfully used for the first Ugi multicomponent synthesis of polyfluoroalkyl-substituted proline, homoproline, and azepan carboxylic acid derivatives. Based on the suggested reaction the first synthesis of dipeptides containing α-CF 3 cyclic amino acids residue was described. The scope and limitations of the approach are discussed.

Biocatalytic iminereduction: A whole‐cell recombinant E. coli system, producing an (S)‐selective imine reductase (IRED) from Streptomyces sp. GF3546, is developed. This biocatalyst is used for the enantioselective reduction of a broad range of substrates such as dihydroisoquinolines and dihydro‐β‐carbolines as well as iminium ions.

enantiomerically pure chiral amines continues to expand, few existing methods provide access to secondary amines. To address this shortcoming, we have over-expressed the gene for an (R)-imine reductase [(R)-IRED] from Streptomyces sp. GF3587 in Escherichia coli to create a recombinant whole-cell biocatalyst for the asymmetricreduction of prochiral imines. The (R)-IRED was screened against a panel of cyclic imines
