This work describes the attachment of two amino acid derivatives by olefin cross-metathesis using Grubbs' second generation catalyst. They were connected at the carboxyl termini. In addition, a cyclic dilactam scaffold was used, which reacted with only a fraction of the amino acid derivatives. The remaining fraction coupled directly coupled with no scaffold. This highly trans-selective double attachment
这项工作描述了使用Grubbs的第二代催化剂通过烯烃交叉复分解连接两个氨基酸衍生物的过程。它们在羧基末端连接。另外,使用环状地内酰胺支架,其仅与一部分氨基酸衍生物反应。其余部分直接偶联而没有支架。这种高度反式选择性的双重连接导致单个反应中多种氨基酸的交叉复分解。
