Tetracyclic Indole Derivatives from the Reaction of Methyl 2,4-Dioxo-6,6-dimethoxyhexanoate with Tryptamine: Indolo[2,3-a]quinolizidine vs 3,7a-Diazacyclohepta[jk]fluorene
摘要:
Depending on the acid used for cyclization, reaction of methyl 6,6-dimethoxy-2,4-dioxohexanoate (4) with tryptamine yielded indoloquinolizidine (8) (AcOH) or diazacycloheptafluorene (10) (TFA). Treatment of 8 with TFA gave 10.
