stereoconservative synthesis of diamine‐based peptidomimetics is described, by split‐Ugi multicomponent reaction, involving chiral N‐protected amino acids and α‐substituted isocyanoacetate. In particular, piperazine and bispidine (3,7‐diazabicyclo[3.3.1]nonane) are exploited as diamine components, bispidine being the first example of a sterically demanding bicyclic system employed in a split‐Ugi reaction.
通过拆分Ugi多组分反应描述了一种简单,一步一步,立体保守的基于二胺的拟肽合成方法,涉及手性N-保护的氨基酸和α-取代的异氰基乙酸酯。特别是,哌嗪和bispidine(3,7-二氮杂双环[3.3.1]壬烷)被利用作为二胺成分,bispidine是在分裂中采用的空间要求的双环系统的第一示例的Ugi反应。
