The organocatalytic kinetic resolution of 4-substituted oxazinones has been optimised (selectivity factor S up to 98, chiral oxazinone ee values up to 99.6% (1a-g) and product ee values up to 90% (3a-g)) in a rational way by applying the Design of Experiments (DoE) approach.

The stereochemistry of a phenylalanine aminomutase (PAM) on the andrimid biosynthetic pathway in Pantoea agglomerans (Pa) is reported. PaPAM is a member of the 4-methylidene-1H-imidazol-5(4H)-one (MIO)-dependent family of catalysts and isomerizes (2S)-α-phenylalanine to (3S)-β-phenylalanine, which is the enantiomer of the product made by the mechanistically similar aminomutase TcPAM from Taxus plants. The NH2 and pro-(3S) hydrogen groups at Cα and Cβ, respectively, of the substrate are removed and interchanged completely intramolecularly with inversion of configuration at the migration centers to form β-phenylalanine. This is a contrast to the retention of configuration mechanism followed by TcPAM.
