Application

(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.
