of silyl enol ethers is superior to the desired condensation in InCl3-catalyzed aldol reactions of silyl enol ethers with aldehydes in water. The reactions were found to proceed in certain amounts in the presence of a catalytic amount of a Lewis acid under neat (solvent-free) conditions, while substrate limitation was observed in these reactions. Use of InCl3 as a Lewis acid in aldol reactions in micellar
与先前的报道相反,发现甲硅烷基烯醇醚的水解优于InCl 3催化的甲硅烷基烯醇醚与醛在水中的醛醇缩合反应中所需的缩合反应。发现在纯净(无溶剂)条件下,在催化量的路易斯酸存在下,反应以一定量进行,而在这些反应中观察到底物受限。还报道了在胶束体系的醛醇缩合反应中使用InCl 3作为路易斯酸。
