Interactions between pyruvic acids and diphenylborinic acid form the basis of an efficient, direct, boron-catalyzed aldol reaction that takes place in water at room temperature with low catalyst loadings. Both boronic and borinic acids function as catalysts, with the latter demonstrating particularly high activity. A wide range of aldehydes, including enolizable species, may be employed, delivering
丙酮酸和二苯基硼酸之间的相互作用形成了有效的,直接的,硼催化的羟醛反应的基础,该反应在室温下于水中以较低的催化剂负载量进行。硼酸和硼酸都起催化剂的作用,后者表现出特别高的活性。可以使用各种各样的醛,包括可烯醇的醛,以高收率递送有用的等渗酸衍生物。
