β-Lactams from tetrahydro-1,2-oxazine-3,6-diones, and a labelling study of the product stereochemistry

Article abstract of DOI:10.1016/0040-4020(95)00737-S

The stereochemistry of the N-C bond-forming step in the photochemical conversion of a tetrahydro-1,2-oxazine-3,6-dione to a β-lactam has been shown to take place with scrambling of stereochemistry using a deuterium labelled precursor.
