A protocol for the diastereoselective synthesis of C-1 indol-3-yl substituted tetrahydroisoquinoline derivatives via Pictet–Spengler condensation with L-DOPA or l-DOPA derivatives and 1H-indole-3-carbaldehydes is presented. The protocol is used for the successful synthesis of several tetrahydroisoquinolines as well as diketopiperazine fused analogues.
提出了通过Pictet-Spengler缩合与L -DOPA或1- DOPA衍生物和1 H-吲哚-3-甲醛进行非对映选择性合成C-1吲哚-3-基取代的四氢异喹啉衍生物的方案。该方案用于成功合成几种四氢异喹啉以及二酮哌嗪融合的类似物。
