Method for preparing polysubstituted benzofuran-4-formic acid compound through ruthenium catalysis
The invention belongs to the technical field of organic synthesis, and discloses a method for preparing a polysubstituted benzofuran-4-formic acid compound through ruthenium catalysis. An m-hydroxybenzoic acid compound, a diaryl alkyne compound, a ruthenium catalyst, an additive and a solvent are subjected to a heating reaction in an air or oxygen environment, and a reaction product is separated and purified, so that the polysubstituted benzofuran-4-formic acid compound is obtained. The ruthenium catalytic system used in the method has high catalytic activity, so that air or oxygen can be used as a green oxidant in the reaction, and toxic, dangerous or expensive oxidants are prevented from being used. The reaction raw materials are easy to obtain, the solvent amount is small, the solvent is insensitive to water, operation is easy, convenient and safe, the method can be well amplified to the gram-level scale, and industrialization is convenient to achieve. The reaction is taken as a key step, the natural product diptoindonesin G with biological activity can be conveniently synthesized, and the diptoindonesinG has a good application prospect.
