Overview

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 isofregenedadio
