Allgemeine Beschreibung

4-Pentenoyl chloride has been identified as a key impurity in 5-chlorovaleroyl chloride (5-CVC). 4-Pentenoyl chloride can be synthesized by reacting thionyl chloride and 4-pentenoic acid.

Anwendung

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.
