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, Research Support, Non-U.S. Gov’t, Journal of Organic Chemistry called Catalytic Synthesis of 3-Thioindoles Using Bunte Salts as Sulfur Sources under Metal-Free Conditions, Author is Qi, Hong; Zhang, Tongxin; Wan, Kefeng; Luo, Meiming, which mentions a compound: 67929-86-6, SMILESS is O=C(C(N1)=CC2=C1C=CC(OC)=C2)OC, Molecular C11H11NO3, Computed Properties of C11H11NO3.
An efficient catalytic method for the synthesis of 3-thioindoles has been successfully developed, which uses odorless, stable, readily available crystalline Bunte salts as the sulfenylating agents, iodine as nonmetallic catalyst, and DMSO as both the oxidant and solvent. This method is practical and environmentally benign in terms of sulfur sources, catalyst, and solvent. The catalytic reaction is selective at the C3 position of indoles and compatible with a wide range of substrates, giving the desired products in good to excellent yields.
Different reactions of this compound(Methyl 5-methoxyindole-2-carboxylate)Computed Properties of C11H11NO3 require different conditions, so the reaction conditions are very important.
