difference in distinguishing substrates of otherwise nearly identical chemical reactivities. A one‐pot cascade reaction involving nitromethane and two aliphatic aldehydes with similar reactivities has been developed (see scheme). The use of a biphasic reaction medium with two different organic catalysts results in the controlled incorporation of both aldehyde substrates into a single major cross‐product
相之间的交叉:极性在区分化学反应性几乎相同的底物方面有所不同。已经开发出一种单锅反应,包括硝基甲烷和两个具有相似反应性的脂族醛(请参见方案)。将双相反应介质与两种不同的有机催化剂一起使用,可以将两种醛底物可控地结合到一个主要的交叉产物中。
