Abstract
Aminoketone derivative compounds containing a heterocyclic ring bonded to an aminoketone moiety and useful as effective ingredients of centrally acting muscle relaxants and pollakiurea curing agents. (+)3-phenyl-5-[2-(1-pyrrolidinylmethyl)butyryl] isoxazole, which has a more remarkable central muscle relaxant action as compared with its racemic modification, can be effectively separated from the racemic modification using optically active 10-camphorsulfonic acid as the agent for the optical resolution.
