N-protected dipeptide esters have been converted into the corresponding protected endothiopeptides1 using Lawesson's reagent,2 1. Methods of amino and carboxyl deprotection, and coupling of the thiopeptides with amino acids have been defined and used to prepare two examples of novel N-protected endothiotripeptide esters with a single thioamide link. Possible effects of the thioamide bond on the conformation
的N-保护的二肽酯已被转换成相应的被保护endothiopeptides 1使用Lawesson试剂,2种的氨基和羧基去保护1.方法,以及与氨基酸的硫肽的联接已经被定义并用于制备新颖的两个例子的N-保护具有单个硫酰胺键的硫代三肽内酯。考虑了硫酰胺键对二肽酯构象的可能影响。
