(R)-(+)-α-Hydroxy-γ-butyrolactone can be used as a starting material to synthesize:
- δ-Azaproline by reacting with benzyloxycarbonyl aminophthalimide via Mitsunobu reactions.
- Homochiral (R)-2,4-dihydroxybutyramide seco-pseudonucleoside reagents.
- Botryolide B via esterification and ring-closing metathesis reaction.
- Pregnane derivatives containing γ-butyrolactones as potential glucocorticoid agonists.
