The present invention concerns a process for creating a Carbon-Carbon bond (C—C) or a Carbon-Heteroatom bond (C—HE) by reacting a compound carrying a leaving group with a nucleophilic compound carrying a carbon atom or a heteroatom (HE) that can substitute for the leaving group, creating a C—C or C—HE bond, wherein the reaction takes place in the presence of an effective quantity of a. a catalytic system comprising a ligand and at least a metal-based catalyst, such a metal catalyst being chosen among iron or copper compounds proviso that only a single metal is present.

A three-step synthesis of masked 2,3-diaminoindole 1 from 2-iodo-3-nitro-1-(phenylsulfonyl)indole (2) has been developed. Treatment of 1 with trifluoroacetic acid generates the unstable 2,3-diamino-1-(phenylsulfonyl)indole (3), which can be trapped with α-dicarbonyl compounds to afford 5H-pyrazino[2,3-b]indoles 7–10.
掩蔽2,3- diaminoindole的三步合成1由2-碘-3-硝基-1-(苯基磺酰基)吲哚(2)已被开发。用三氟乙酸处理1会生成不稳定的2,3-二氨基-1-(苯磺酰基)吲哚(3),可以将其与α-二羰基化合物截留,得到5 H-吡嗪并[2,3- b ]吲哚7 – 10。
