Aldol reactions on solid phase have been achieved. In the presence of a catalytic amount of scandium triflate (Sc(OTf)3), polymer-supported silyl enol ethers reacted with aldehydes to afford the corresponding β-hydroxy thioester derivatives, which were reduced to 1,3-diol and β-hydroxy aldehyde derivatives, or hydrolyzed to β-hydroxy carboxylic acid derivatives.
已经实现了固相上的醛醇缩合反应。在催化量的三氟甲磺酸scan(Sc(OTf)3)存在下,聚合物负载的甲硅烷基烯醇醚与醛反应,得到相应的β-羟基硫代酯衍生物,将其还原为1,3-二醇和β-羟基醛衍生物,或水解为β-羟基羧酸衍生物。
