Application

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.

1-Ethyl-3-[3-dimethylaminopropyl]carbodiimide (EDC) is a commonly used reagent for bioconjugation and peptide synthesis. Both EDC and the corresponding urea derivative, 1-(3-dimethylaminopropyl)-3-ethylurea (EDU), are achiral. As the reagent is active in aqueous solutions, it is a common choice for the study of
