A general synthetic entry to Strychnos alkaloids of the curan type via a common 3a-(2-nitrophenyl)hexahydroindol-4-one intermediate. Total syntheses of (±)- and (-)-tubifolidine, (±)-akuammicine, (±)-19,20-dihydroakuammicine, (±)-norfluorocurarine, (±)-ec

A general strategy for the synthesis of pentacyclic Strychnos alkaloids with the curan skeleton has been developed. It utilizes 3a-(2-nitrophenyl)hexahydroindol-4-one (23), which was prepared from 2-allyl-2-(2-nitrophenyl)-1,3-cyclohexanedione (15), as th
