Synthesis and separation of diastereoisomeric 1-aryl-3-piperidino(morpholino)-2-phenylpropan-1-ols and their hydrochlorides
摘要:
1-Aryl-3-piperidino(morpholino)-2-phenylpropan-1-ols were synthesized by reduction of the corresponding 1-aryl-3-piperidino(morpholino)-2-phenylpropan-1-ones with lithium tetrahydridoaluminate, and the products were separated into erythro and threo isomers by fractional crystallization. Their relative configuration and diastereoisomeric purity was determined by H-1 NMR spectroscopy.
