Adding a certain compound to certain chemical reactions, such as: 34846-90-7, name is Methyl 3-methoxyacrylate, belongs to esters-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 34846-90-7, HPLC of Formula: C5H8O3
A mixture of Intermediate-8C (1 equiv) and methyl 3-methoxyacrylate (3 equiv) was stirred at 90 °C for 6 h. The solvent was removed in vacuo and purification by silica gel chromatography (0-7percent methanol/dicloromethane) delivered the desired compound as a colorless solid (41percent). Intermediate-11: 1H NMR (400 MHz, CDC13) delta 10.46 (br s, 1H), 8.51 (d, 1H), 7.96 (d, 1H), 7.31 (s, 1H), 7.31-7.24 (m, 1H), 7.07-7.02 (m, 3H), 6.60 (d, 1H), 6.38 (d, 1H), 5.89 (s, 2H).
