The activating effect of pi complexation of a Cr(CO)3 unit allows selective nucleophilic substitution in indoles such as tryptophan derivatives and provides intermediates for the synthesis of clavicipitic acid and related indole natural products.
Cr(CO)3单元的pi络合的激活作用可在吲哚(例如色氨酸衍生物)中选择性地进行亲核取代,并提供合成克拉维酸和相关吲哚天然产物的中间体。
