β-Butyrolactone undergoes ring opening polymerization in the presence of ethoxy-bridged dinuclear indium catalyst to yield biodegradable polyester poly(hydroxybutyrate). Polymerization of racemic β-butyrolactone in the presence of chiral initiators has been reported. It is versatile building block for organic synthesis.
Application：
β-Butyrolactone was used in the preparation of (3-O-[oligo-(3-hydroxybutyrate ester)] fluorescein, fluorescein derivative of poly(3-hydroxybutyrate) via anionic polymerization.
