Stereoselective synthesis of N-Cbz-substituted β-amino ketones exploiting the versatile 1,3-oxazin-6-one scaffold is reported. The 4-substituted 1,3-oxazinan-6-ones were enolized and acylated diastereoselectively by addition of various acyl halides. Acidic decarboxylation was then employed to smoothly transform the 5-acylated products to chiral β-amino ketones. This methodology further highlights the utility of the 1,3-oxazinan-6-one as a scaffold to access valuable synthons that are used in the peptidomimetic field. © Georg Thieme Verlag Stuttgart · New York.
