A novel, nitrone-ketene acetal based approach to enantiopure (2S,3S)-N-benzoyl- and N-boc-phenylisoserine has been realized. The convergent approach, which involves the intermediacy of isoxazolidinones, proceeds in up to 59% overall yield and requires only three operations from the starting nitrones.
