  日期：2011.11.1

  Synthesis of Nα-protected amino acyl azides starting from corresponding acids via the carbonyldiimidazole (CDI) activation is described. The protocol is extended for a one-pot preparation of ureido peptides that circumvents the isolation of acyl azide and isocyanate intermediates. The reaction was accomplished without using any additives and base. The protocol is simple, clean, high yielding and free

  描述了通过羰基二咪唑（CDI）活化从相应的酸开始合成Nα-保护的氨基酰基叠氮化物。该协议扩展为一锅式制备脲基肽，可避免酰基叠氮化物和异氰酸酯中间体的分离。不使用任何添加剂和碱即可完成反应。该方案简单，清洁，高收率且无消旋作用。

  Dolastatin 10 (1) is a potent antineoplastic pentapeptide. Novel dolastatin 10 analogs each modified at one of the constituent amino acid derivatives, were synthesized and their antitumor activity was evaluated against P388 leukemia in mice. The structural requirements for antitumor activity are discussed. Some of the analogs, 31c, 35c, 38b, and 50c showed excellent activity in vivo. Highly active 50c
