  描述：

  (2R,2'R)-2,2'-ethano-cyclo(Pro-Pro) 在 N-甲基吗啉 、 盐酸 、 2-氯-1-甲基吡啶碘化物 作用下， 以 二氯甲烷 为溶剂， 反应 12.0h， 生成 methyl (6R,8aR)-1'-[(2S)-1-[(2-methylpropan-2-yl)oxycarbonyl]pyrrolidine-2-carbonyl]-5-oxospiro[2,3,7,8-tetrahydro-1H-indolizine-6,2'-pyrrolidine]-8a-carboxylate

  Concerted Synthesis of a Spirobicyclic Type-VI β-Turn Mimic of Pro-Pro-Pro-NH₂

  摘要：

  A highly concerted strategy for the synthesis of symmetrical type-VI beta-turn mimics was formulated. A proof of concept is presented in the synthesis of a spirobicyclic peptidomimetic of Pro-Pro-Pro-NH2, compound 6. The formation of an unusual adduct that was encountered in the process also is reported. This approach is potentially general for type-VI beta-turn mimics where the i + 1 and i + 2 residues are identical.
