[reaction: see text] An efficient two-pot, asymmetricsynthesis of benzothiadiazine-substituted tetramic acids is reported. Starting from commercially available alpha-amino acids or esters, reductive amination followed by a novel one-pot amide bond formation/Dieckmann cyclization provided the desired products in high yield and opticalpurity. An analogous solid-phase approach to the same targets is
