Our auxiliary-based method for the synthesis of bis(lactams) has been optimized. A novel auxiliary is described that is inserted in the backbone of a linear peptide facilitating the mutually reactive terminal groups to approach one another for a cyclization reaction. A subsequent ring contraction mechanism leads to the bis(lactams) with the remainings of the auxiliary still attached. Functionalized seven-
我们基于辅助的双(内酰胺)合成方法已得到优化。描述了一种新型辅助剂,其插入线性肽的骨架中,促进相互反应的末端基团相互接近以进行环化反应。随后的环收缩机制导致双(内酰胺)与辅助剂的剩余部分仍然连接。已经制备了使用传统方法难以获得的功能化的七元和八元双(内酰胺)。从双(内酰胺)中去除助剂已经描述了可能发生的副反应。
