| 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. |
| General description: | 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. |
