Pike, Ryan A. S. published the artcileK2CO3-Catalyzed Synthesis of 2,5-Dialkyl-4,6,7-tricyano-Decorated Indoles via Carbon-Carbon Bond Cleavage, SDS of cas: 5340-78-3, the publication is Organic Letters (2020), 22(8), 3268-3272, database is CAplus and MEDLINE.
A novel method to synthesize 2,5-dialkyl-4,6,7-tricyanoindole derivatives from a base-catalyzed reaction of 1,3-diketones with fumaronitrile was described. The reaction proceeded by the condensation of two mols. of fumaronitrile and one mol. of 1,3-diketone in a remarkable process that involved the cleavage of one C(sp3)-C(sp2) bond in 1,3-diketones and the formation of one carbon-nitrogen bond and four carbon-carbon bonds to construct both the aryl and pyrrole rings of the indole in one step.
