reagents was used to complete the first known synthesis of the natural marine cyclodepsipeptide IB-01212. The cyclic, symmetric octapeptide contains two of each of the following residues: l-N,N-Me2Leu, l-Ser, l-N-MeLeu and l-N-MePhe. IB-01212 also features two symmetric ester bonds between the hydroxyl group of Ser and the carboxyl function of the N-MePhe. Total solid-phase syntheses of the product was
合成设计,正交保护基和偶联剂的合适组合用于完成天然海洋环二肽IB-01212的第一个已知合成。环状,对称八肽包含两个各以下残基组成:升- ñ,N-我2亮氨酸,升-Ser,升- N- MeLeu和升- Ñ -MePhe。IB-01212在Ser的羟基和N的羧基官能团之间还具有两个对称的酯键-MePhe。产物的总固相合成是通过三种不同的途径并行进行的:杂多片段的二聚化,线性合成和会聚合成。收敛策略在产物产率和纯度方面给出了最好的结果,并且特别适合于IB-01212和类似肽的大规模合成。
