Recent Advances

Poly(α-hydroxy acids), as a family of biodegradable polyesters, are valuable materials due to their broad applications in packaging, agriculture, and biomedical engineering. Herein we highlight and explore recent advances of catalysts in controlled ring-opening polymerization of O-carboxyanhydrides towards functionalized poly(α-hydroxy acids), especially metal catalyst-mediated controlled polymerization. Limitations of current polymerization strategies of O-carboxyanhydrides are discussed.

Hydroxy Acids

Lithium naphthalenide reacts with carboxylic acids in the presence of diethylamine to give the α-anions of lithium carboxylates. Reaction of these anions with various epoxides gives the corresponding y-hydroxy acids in good yield. The γ-hydroxy acids easily cyclize to give γ-butyrolactones.
