ABSTRACT:
A Process for Preparing L-(-)-carnitine is disclosed which comprises acylating D-(+)-carnitinenitrile or D-(+)-carnitineamide to their respective acyl derivatives which, via acid hydrolysis, yield D-(+)-carnitine which is converted to the lactone of L-(-)-carnitine. The lactone when in base yields L-(-)-carnitine.
