Nonracemic cinnamyl imidazolidinylenepalladium complexes such as I (R = Et2CH) are prepared as catalysts for the chemoselective and enantioselective arylation of N-(2-bromophenyl) allyl-substituted acetamides such as II (R1 = Ph, 1-naphthyl, 2-naphthyl, 2-MeC6H4, 2-FC6H4, 2-MeOC6H4, 4-MeC6H4, 4-FC6H4, 4-F3CC6H4, 4-PhC6H4, 3-MeC6H4, 3-FC6H4, 3-MeOC6H4, 3,5-Me2C6H3, 1-Me-3-indolyl, Me; R2 = H, Me; R3 = H, MeO) to give nonracemic (aryl)(allyl)oxindoles such as III (R1 = Ph, 1-naphthyl, 2-naphthyl, 2-MeC6H4, 2-FC6H4, 2-MeOC6H4, 4-MeC6H4, 4-FC6H4, 4-F3CC6H4, 4-PhC6H4, 3-MeC6H4, 3-FC6H4, 3-MeOC6H4, 3,5-Me2C6H3, 1-Me-3-indolyl, Me; R2 = H, Me; R3 = H, MeO) in 40-98% yields and in 4-91% ee (with all but three of the 21 examples in 69-91% ee) with none of the isomeric benzazepinone products formed in most cases. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-indoleacetic acid (cas: 1912-48-7Application In Synthesis of 1-Methyl-3-indoleacetic acid).
1-Methyl-3-indoleacetic acid (cas: 1912-48-7) belongs to indole derivatives. The indole subunit is an almost ubiquitous component of biologically active natural products, and its study has been the focus of research for decades. They are capable of binding to a variety of receptors with high affinity and thus have applications in a wide range of therapeutic areas.Application In Synthesis of 1-Methyl-3-indoleacetic acid
