Synthesis of α,ω‐Diazidoalditol Derivatives via Both bis‐ or tris‐Cyclic Sulfites and Peracetylated α,ω‐Dibromoalditols as Bielectrophilic Intermediates

Abstract The α,ω‐diazidoalditol derivatives with erythro, threo, xylo, ribo, D‐arabino, D‐manno, and D‐gluco configuration were efficiently synthesized, respectively, from bis‐ or tris‐cyclic sulfite or peracetylated α,ω‐dibromoalditol intermediates. The cyclic sulfite intermediates has the advantage to lead directly to the free α,ω‐diazido‐α,ω‐dideoxyalditols.
