4-Pentyn-1-ol Usage And Synthesis

Chemical Properties

Clear yellow liquid

Uses

4-Pentyn-1-ol is an alkyne alcohol that is used as an initiator in ring-opening polymerization reactions. 4-Pentyn-1-ol is capable of undergoing cyclosisomerization, and is also used as a reactant in the synthesis of (+)-Serinolamide A, a cannabinoid CB1 receptor agonist.

General Description

Mechanism of (THF)W(CO)₅-promoted endo- and exo-cycloisomerization of 4-pentyn-1-ol was studied.
