近年来,对于固相合成技术及高分子试剂在有机合成中的应用已有报道。在高聚物中引入功能团的高分子试剂与相应的低分子试剂比较,具有合成操作简便、选择性好等的优点,同时还能固定底物,有利于单功能团的转化及不对称合成。用2％对二乙烯基苯交联聚合的聚苯乙烯(简称聚苯乙烯珠体,缩写为 )作载体的聚苯乙烯二苯膦 In recent years, the application of solid-phase synthesis technology and polymer reagents in organic synthesis has been reported. Compared with the corresponding low molecular weight reagent, the polymer reagent with functional groups introduced into the polymer has the advantages of simple and convenient synthesis, good selectivity and the like, and at the same time, it can fix the substrate and is conducive to the conversion of the functional group and the asymmetric synthesis . Polystyrene diphenylphosphine, crosslinked with 2% p-divinylbenzene (abbreviated to polystyrene beads, abbreviated as)
