【摘要】 在前人工作基础上成功地拆分了１ ，１′－ 联－ ２ － 萘酚，获得了高产率和高对映过剩（ｅ．ｅ ．） 值的光学活性的１ ，１′－ 联－ ２ － 萘酚。在手性季铵盐的制备过程中，考虑到清洁生产的问题，尝试了不同溶剂对产物产率和ｅ．ｅ．值的影响，最后选用丙酮和少量乙醇作为溶剂，取得了较好的结果。更多还原

【Abstract】 Racemic 1,1′-bi-2-naphthol was resolved successfully on the basis of several chemists′ works.One of the features of the work is the consideration of cleaning production and several solvents have respectively been attempted in the preparation of chiral N-benzylcinchonidinium chloride.Eventually,acetone with a little ethanol is chosen as the best solvent system and optically active 1,1′-bi-2-napthol was obtained with high yield and e.e.value.更多还原
