Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Organic Letters called Organocatalytic Formal (3+2) Cycloaddition toward Chiral Pyrrolo[1,2-a]indoles via Dynamic Kinetic Resolution of Allene Intermediates, Author is Bai, Jian-Fei; Zhao, Lulu; Wang, Fang; Yan, Fachao; Kano, Taichi; Maruoka, Keiji; Li, Yuehui, which mentions a compound: 1219741-50-0, SMILESS is CC1=CNC2=C1C=CC(Br)=C2, Molecular C9H8BrN, Application In Synthesis of 6-Bromo-3-methyl-1H-indole.
The chiral phosphoric acid catalyzed formal (3+2) cycloaddition of 3-substituted 1H-indoles and propargylic alcs. containing a functional directing group (p-NHAc or p-OH) was reported. A straightforward method to synthesize chiral pyrrolo[1,2-a]indole bearing a tetrasubstituted carbon stereocenter was represented. The reaction proceeded smoothly with a wide array of substrate tolerance to deliver various chiral pyrrolo[1,2-a]indoles in up to 93% yield and 98% ee. The utility of this method is highlighted by the diverse transformations of the products into various indole derivatives
As far as I know, this compound(1219741-50-0)Application In Synthesis of 6-Bromo-3-methyl-1H-indole can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
