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, RSC Advances called Rhodium(II)-catalyzed intramolecular annulation of 1-sulfonyl-1,2,3-triazoles with indoles: facile synthesis of functionalized tetrahydro-β-carbolines, Author is Shang, Hai; Tian, Yu; Luo, Jun; Li, Lingyu; Tang, Yefeng; Zou, Zhongmei, the main research direction is indolyl sulfonyltriazole preparation rhodium catalyst intramol cyclization; tetrahydro carboline preparation.Safety of 5-Methoxy-1H-indole-2-carbaldehyde.
A novel rhodium(II)-catalyzed intramol. annulation of 1-sulfonyl-1,2,3-triazoles with indoles was developed, which enabled the facile synthesis of various 4-functionalized tetrahydro-β-carbolines as well as relevant scaffolds from readily available starting materials.
From this literature《Rhodium(II)-catalyzed intramolecular annulation of 1-sulfonyl-1,2,3-triazoles with indoles: facile synthesis of functionalized tetrahydro-β-carbolines》,we know some information about this compound(21778-81-4)Safety of 5-Methoxy-1H-indole-2-carbaldehyde, but this is not all information, there are many literatures related to this compound(21778-81-4).
