The addition of acyl anion equivalents to aliphatic aldehydes (crossed-acyloin reaction) has been developed. Cesium fluoride with isopropanol as solvent promotes the addition of O-silyl thiazolium carbinols to various aliphatic aldehydes in moderate to good yields. These reactions represent a general procedure for the selective coupling of aliphatic aldehydes by an acyl anion reaction which have been problematic until now.
已开发出将酰基阴离子等价物与脂肪醛进行加成的反应(交叉酸醇反应)。氟化铯与异丙醇作为溶剂促进了O-硅基噻唑鎓醇与多种脂肪醛的加成反应,产率为中等到良好。这些反应代表了一种通过酰基阴离子反应选择性耦合脂肪醛的通用程序,而这一过程直到现在仍然存在问题。
