Regiodivergent formal [5+2]- and [4+2]-annulation reactions of indole derivatives with 2-(2-alkynyl)aryl cyclopropane-1,1-diesters (ACPs) was developed. A series of tetracyclic indole derivatives were delivered in a 77% average yield with excellent regioselectivities enabled by Au(I)/Sc(III) bimetallic relay catalysis. A gram-scale reaction and further transformation of the resulting tetracyclic indoles demonstrated the practical utility of this protocol. Moreover, the photophys. properties of the obtained multicyclic compounds were also investigated.Trimethylsulfoxonium iodide(cas: 1774-47-6Related Products of 1774-47-6) was used in this study.
Trimethylsulfoxonium iodide(cas: 1774-47-6) reacts with sodium hydride to prepare dimethyloxosulfonium methylide, which is used as a methylene-transfer reagent in synthetic chemistry. It is used to prepare ylide, which reacts with carbonyl compounds to get epoxides.Related Products of 1774-47-6
