  Synthesis and Conformational Analysis of meso-Ter(1,3-dioxan-4-yls)

  摘要：

  A convergent synthesis of the meso-ter(1,3-dioxanyls) 8-11 has been achieved, starting from two enantiomeric building blocks in each case. The stereogenic centres in the central linkage region were set up by stereocontrolled aldol additions. Structure assignment of the final products was based on comparisons between experimental and calculated (3)J(H,H) coupling constants, which reflect distinct conformer populations.
