A polystyrene-supported BINOL-derived chiral phosphoric acid has been applied to the desymmetrisation of -diones to produce enantioenriched cyclohexenones. The catalytic resin has proven highly active and robust, giving rise to Hajos-Parrish or Wieland-Miescher type products in good yields and enantioselectivities, while allowing for extended recycling.
一种聚苯乙烯负载的联萘酚衍生的手性磷酸已被应用于二酮的去对称化反应，以制备对映体富集的环己烯酮。这种催化树脂已被证明具有高活性和稳定性，能以良好的产率和对映选择性得到哈约什-帕里什型或维兰德-米舍尔型产物，同时还能多次循环使用。
