Abstract
DL-threo-1-(p-nitro-phenyl)-2-amino-1,3-propane-diol-hydroc hlorid- e is prepd. by a Meerwein-Porndof redn. of p-nitro-acetamido -beta-hydroxy-propio-phenone with aluminium-iso-propoxide in an iso-propyl-alcoholic medium. The redn. complex is decomposed by water. The obtd. DL-threo-1-(p-nitro -phenyl)-2-acetemido -1,3-propane-diol is hydrolised and converted to DL-threo-1-(p-nitro-phenyl)2-amino -1,3-propane-diol-hydrochloride. The reaction is carried out in one step without isolating of DL-threo-1-(nitro-phenyl) -2-amino-1,3-propane-diol.
