Adding a certain compound to certain chemical reactions, such as: 575-03-1, 7-Hydroxy-4-(trifluoromethyl)coumarin, 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, Product Details of 575-03-1, blongs to alcohols-buliding-blocks compound. Product Details of 575-03-1
General procedure: To a magnetically-stirred solution of 7-hydroxycoumarin derivatives (2 mmol), aromatic aldehydes (2 mmol) and NEt3 (2 mmol) in THF (8 mL) a mixture of dialkyl acetylenedicarboxylate (2 mmol) in THF (2 mL) was added in 15 min. The reaction mixture was then allowed to stand at room temperature for 0.5-10 h. After completion of the reaction as indicated by thin-layer chromatography (TLC) (n-hexane/EtOAc, 1:1), the solvent was removed under reduced pressure. The residue was purified by column chromatography on silica gel (Merck, 230-400 mesh) using a mixture of n-hexane/EtOAc (1:1) as eluent to afford the pure product as a light yellow powder.
The synthetic route of 575-03-1 has been constantly updated, and we look forward to future research findings.
