Uncatalyzed cycloaddition of 3,4‐dihydroisoquinolines to (E)‐1,1,1‐trifluoro‐3‐nitro‐2‐butene via Grob reaction provide a simple one‐step route to the 5,6‐dihydropyrrolo[2,1‐a]isoquinolines, which represent the basic structural framework of the antitumor active alkaloid crispine.
通过Grob反应将3,4-二氢异喹啉未催化环加成至(E)-1,1,1-三氟-3-硝基-2-丁烯,提供了一条简单的一步路线,即到达5,6-二氢吡咯并[2,1- a ]异喹啉,代表抗肿瘤活性生物碱脆皮的基本结构框架。
