Enantiopure aminopyrans by a lewis acid promoted rearrangement of 1,2-oxazines: Versatile building blocks for oligosaccharide and sugar amino acid mimetics

1,3-Dioxolanyl-substituted 1,2-oxazines, such as syn-l and anti-1, rearrange under Lewis acidic conditions to provide bicyclic products 2-5. Subsequent reductive transformations afforded enantiopure 3-aminopyran derivatives such as 7 and 9 or their protec

Simple modifications of enantiopure 1,2-oxazines leading to building blocks for carbohydrate and peptide mimetics

Starting from easily available enantiopure pyran derivatives we prepared bicyclic γ-lactam 6, azide 10, and alkyne 18 using simple procedures. These compounds were crucial intermediates for the synthesis of γ-amino acid 8 and dipeptide 9 as well as triazo
