Abstract
Abstract A synthesis of all four stereoisomers of the unnatural amino acid β-OH Dab (α, γ- diamino butyric acid) in orthogonally protected form is described. The synthetic strategy relies on a three-step sequence comprising stereoselective dihydroxylation, sulfite formation, and regioselective sulfite opening with azide to build the densely functionalized carbon skeleton.
