2-tert-prenyltryptamines with N-bromosuccinimide gives clean access to the marine natural product flustramine C and analogues with the tert-prenyl group shifted to the 3a-position of the resulting pyrrolo[2,3-b]indole (70-80%). Dihydroflustramine C was obtained by DIBAL-H reduction of flustramine C. Bromination or N-methylation of the indole moiety does not influence the course of the rearrangement. alkaloids - flustramines
用N-溴丁二酰亚胺处理2-叔戊烯基色胺可以使海洋天然产物氟他胺C和叔戊烯基移至所得吡咯并[2,3- b ]吲哚的3a-位的类似物(70- 80%)。通过DIBAL-H还原氟雌胺C获得二氢氟雌胺C。吲哚部分的溴化或N-甲基化不影响重排的过程。 生物碱-氟他胺-吲哚-海洋天然产物-异戊二烯迁移
