Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 21778-81-4, is researched, SMILESS is O=CC(N1)=CC2=C1C=CC(OC)=C2, Molecular C10H9NO2Journal, Article, Angewandte Chemie, International Edition called Catalysis based on C-I···π halogen bonds: electrophilic activation of 2-alkenylindoles by cationic halogen-bond donors for [4+2] cycloadditions, Author is Kuwano, Satoru; Suzuki, Takumi; Yamanaka, Masahiro; Tsutsumi, Ryosuke; Arai, Takayoshi, the main research direction is alkenylindole iodoimidazolium triflate catalyst diastereoselective cycloaddition; indolyl tetrahydrocarbazole preparation; cycloaddition; density-functional calculations; halogen bonding; heterocycles; noncovalent bonds.Recommanded Product: 5-Methoxy-1H-indole-2-carbaldehyde.
Homo- and cross-[4+2] cycloadditions of 2-alkenylindoles catalyzed by cationic halogen-bond donors were developed. Under mild reaction conditions, 3-indolyl-substituted tetrahydrocarbazole derivatives were obtained in good to excellent yields. Exptl. and quantum calculation studies revealed that the electrophilic activation of 2-alkenylindoles was achieved by C-I···π halogen bonds.
