A mild and catalyzed alternative to the direct aldol reaction has been developed based on the gold‐catalyzed methoxy group transfer from dimethyl acetals to terminal alkynes. Due to the simultaneous activation of the acetals, this aldol approach is only functional for acetals but not aldehydes. A ligand effect from the gold complex has also been observed.
基于金催化的甲氧基从二甲基乙缩醛到末端炔烃的转移,已经开发出了一种温和且可催化的直接羟醛反应的替代方法。由于乙缩醛的同时活化,该醇醛缩醛方法仅对乙缩醛起作用,而对醛没有作用。还观察到了来自金络合物的配体效应。
