D-(-)-Pantolactone is a chiral auxiliary used in many asymmetric synthesis reactions.It can be used as a chiral starting material to synthesize:An insect sex pheromone named 1S,2S,3R-1-acetoxymethyl-2,3,4,4-tetrameth-ylcyclopentane.(-)-Enantiomer of (R)-8-hydroxy-4,7,7-trimethyl-7,8-dihydrocyclopenta[e]isoindole-1,3(2H,6H)-dione, a norsesquiterpene alkaloid.A bicyclic diterpene named isofregenedadiol.
Pantolactone serves as a versatile building block in synthetic organic chemistry, enabling efficient access to pantoyl derivatives and related lactones. Its well-defined reactivity facilitates functionalization at the C2 position, supports orthogonal transformations in complex molecule synthesis, and functions reliably in multistep sequences involving amine coupling or reduction. Bench-stable and readily purified by distillation, it is a practical choice for medicinal chemistry campaigns and process development.
