Triple play: The title reaction of 1 with simple aldehydes gives 3,5,7‐trisilyloxy aldehydes in high yields and diastereoselectivities with extremely low catalyst loading (see scheme). Iodobenzene facilitates the third aldol reaction by apparently acting as a Lewis base towards the silyl catalyst. Tf=trifluoromethanesulfonyl.
三重作用:1与简单醛的标题反应以高收率和非对映选择性和极低的催化剂负载量生成3,5,7-三甲硅烷基氧基醛(请参阅方案)。碘苯通过明显地充当朝向甲硅烷基催化剂的路易斯碱来促进第三羟醛反应。Tf =三氟甲磺酰基。
