Abstract

A process for producing ( S_-B-hydroxy-y-butyrolactone, a versatile intermediate used in several organic sintheses, from (S)-carnitine which is an unexpensive waste-product obtained from the production of (R)-carnitine by the resolution of eacemic mixtures beng kept at 100-190 degree C for 0.5 to 5 hours.
