substrates for a one-pot, two-step multi-bond-forming process leading to the general preparation of aminoindenes and amino-substituted 1,4-dihydronaphthalenes. The synthetic utility of the privileged structures formed from this one-pot process was demonstrated with the total synthesis of four oxybenzo[c]phenanthridine alkaloids, oxychelerythrine, oxysanguinarine, oxynitidine, and oxyavicine.

已经设计了带有2-乙烯基或2-烯丙基芳基的烯丙基三氯乙酰亚氨酸酯作为一锅两步多键形成方法的底物,从而导致氨基茚和氨基取代的1,4-二氢萘的一般制备。从一锅法形成的特权结构的合成效用已通过四种氧苯并[ c ]菲啶生物碱,氧白屈菜红碱,氧血胍,氧硝啶和氧鸟嘌呤的总合成得到证明。分子内的联芳基Heck偶联反应,使用Hermann-Beller palladacycle催化,可用于完成天然产物合成过程中的关键步骤。
