indole‐3‐carbinol and 3,3‐diindolylmethane show bioactivity in a number of disparate disease areas, including cancer, prompting substantial synthetic analogue activity. We describe a new approach to highly functionalised derivatives that starts from allene gas and proceeds via the combination of a three‐component Pd0‐catalysed cascade with a one‐pot, three‐component carbophilic PtII cascade linked to a stereoselective
天然存在的吲哚-3-甲醇和3,3-二吲哚甲烷在许多不同的疾病领域(包括癌症)均具有生物活性,从而促进了合成类似物的大量活性。我们描述了一种新的方法,该方法可以从丙二烯气体开始,然后通过三组分Pd 0催化级联反应与单锅,三组分嗜碳Pt II级联反应与立体选择性酸催化曼尼希反应相结合,来进行高官能化衍生物的合成。–Michael反应生成复杂的环丙基二吲哚基甲烷,对前列腺癌细胞系表现出选择性活性。
