text] 9,9'-Spirobifluorene-1,1'-diol (SBIFOL) was conveniently synthesized from 1,2-dibromobenzene and 3-bromoanisole in high yield. Both enantiomers of SBIFOL were obtained in 99% ee by inclusion resolution with 2,3-dimethoxy-N,N,N',N'-tetracyclohexylsuccinamide. The absolute configurations were determined by X-ray analysis of a single crystal of molecular complex.
[反应:见正文]由1,2-二溴苯和3-溴茴香醚可方便地以高收率合成9,9'-螺双芴-1,1'-二醇(SBIFOL)。通过用2,3-二甲氧基-N,N,N′,N′-四环己基琥珀酰胺进行夹杂物拆分,以99%ee获得了SBIFOL的两种对映体。绝对构型通过分子复合物单晶的X射线分析确定。
