Orthogonally protected polyamines (PAs) have been synthesized using α,ω-diamines and ω-aminoalcohols as N-Cx-N and N-Cy synthons, respectively, and the Mitsunobu reaction as the key reaction for the assembly of the PA skeleta. The Trt, Dde, and Phth groups have been employed for protecting the primary amino functions and the Ns group for activating the primary amino functions toward alkylation and
已经使用 α,ω-二胺和 ω-氨基醇分别作为 N-Cx-N 和 N-Cy 合成子合成了正交保护的多胺 (PA),并且 Mitsunobu 反应是 PA 骨架组装的关键反应。Trt、Dde 和 Phth 基团已用于保护伯氨基功能,Ns 基团用于激活伯氨基功能以实现烷基化和仲氨基功能保护。该方法很容易扩展以适应蜘蛛毒素 Agel 416 和 HO-416b 的全合成,分别包含 3-4-3-3 和 3-3-3-4 PA 骨架。
