β-Dipeptides containing allyl groups at different positions on the peptide backbone were prepared. Ring-closing metathesis of these β-dipeptides with the use of a ruthenium catalyst led to medium-sized cyclic β-dipeptides and macrocyclic tetrapeptides, depending on the nature of the allylic substitution on the β-dipeptides.
制备在肽骨架不同位置含有烯丙基的β-二肽。使用
钌催化剂对这些 β-二肽进行闭环复分解产生中等大小的环状 β-二肽和大环四肽,这取决于 β-二肽上烯丙基取代的性质。
