The macrocyclization of 2 was accomplished through a Mitsunobu reaction using triphenylphosphine and 1,1'-(azodicarbonyl)dipiperidine (ADDP), to afford novel 16- and 17-membered proline-based macrocyclic compounds of type 3.
从N-Cbz-4-羟基脯氨酸甲酯1开始,三氟化硼-二乙基醚化物催化的反应提供了4-叔烷基醚脯氨酸4。两个脱保护基和酰胺键的形成提供了酚醇2。完成了2的大环化通过使用三苯基膦和1,1'-(偶氮二羰基)二哌啶(ADDP)的Mitsunobu反应,得到3型新型16和17元脯氨酸基大环化合物。
