Indolylquinolines,Indolylacridines,和Indolylcyclopenta的合成[ b ]从所述的Baylis-希尔曼加合物喹啉:在原位[1,3]的吲哚核来访问Indolylacridines和Indolylcyclopenta [的-Sigmatropic重排b ]喹啉
摘要:
一种简单易行的途径,可通过C-烷基化的吲哚衍生物的还原环化反应,合成各种结构多样的吲哚基喹啉,吲哚基吡啶和吲哚基环戊[ b ]喹啉衍生物,描述。在含有吲哚的α-区域选择性B–H加合物的还原环化过程中,观察到吲哚核的不寻常的原位[1,3]-σ重排,产生吲哚基吡啶和吲哚基环戊[ b ]喹啉衍生物。

A new and simple method for the C-alkylation of indoles by various Baylis–Hillman adducts and the one-pot reductive cyclization of C-alkylated indole derivatives generated from 2-nitro-Baylis–Hillman adduct to form indolylquinoline derivatives is described.
