DETAILS

Description (English)

Application
Used in the preparation of an acyclic tripeptide containing a heterochiral D-pro-L-pro template with a propensity to exist as a 310 helical conformation. Cyclization via olefin metathesis (Grubbs Catalyst) provides the coresponding tetrapeptide without disruption of the helical conformation.1
Packaging
5, 25 mL in glass bottle

Description (简体中文)

Application
用于制备含左右异向 D-pro-L-pro 模板的无环三肽，该模板倾向于以 310 螺旋构象的形式存在。通过烯烃复分解进行的环化反应（Grubbs 催化剂）可在不破环螺旋构象的情况下生成对应的四肽。1
