A practical and convenient organocatalytic strategy is developed to provide a direct route to syn-selective aldol products in the presence of water. The siloxy serine organocatalyst mediates the direct aldol reaction of TBSO-protected hydroxyacetone with a variety of aldehydes to provide the aldol products in good yields and enantioselectivities up to 92%.
开发了一种实用且方便的有机催化策略,以提供在存在水的情况下合成选择性醛醇产物的直接途径。甲硅烷氧基丝氨酸有机催化剂介导TBSO保护的羟基丙酮与各种醛的直接羟醛反应,从而以高收率和高达92%的对映选择性提供羟醛产物。
