Two-Directional Synthesis of 2,6-Dimethylpyrrolo[2,3-f]indole-4,8-dione by Double Claisen Rearrangement and Nitrene Cyclization
摘要:
Double Claisen rearrangement of the bis-allyl ether of 2,5-dichloro-1,4-hydroquinone, followed by alkene isomerization, oxidation and double chloride displacement with azide gives 2,5-diazido-3,6-dipropenyl-1,4-benzoquinone. Upon heating, a double nitrene cyclization occurs completing a high yielding, two-directional route to the pyrrolo[2,3-f]indole-4,8-dione ring system.
