2,3-Isopropylidene ribonic acid, 1,4-lactones

Racemic carboxylic acids are resolved into their enantiomers using optically active enantiomers of four lactones as resolving agents. The four lactones are 2,3-isopropylidene-ribonic acid-1,4-lactone, 1,2-isopropylideneglucofuranurono-3,6-lactone, 2-hydroxy-3,3-dimethyl-1,4-butyrolactone and 3,4-isopropylidene-arabino-1,5-lactone. Novel diastereoisomeric esters of the acids with the lactones are disclosed.
