Zusammenfassung

N-Boc-protected serine and threonine esters could be readily added to 2-nitroglycals, affording exclusively α- and β-anomers with galacto- and gluco-configuration, respectively. Nitro group reduction to the amino group and also ester cleavage led to compounds 2, 6, and 11, which can be regarded as dipeptide mimetics. From these compounds, bicyclic pyrano[2.3-b][1,5]oxazepines 7–14 were prepared by ring closure.
