Abstract: The present invention provides a method for preparing a resveratrol compound, and belongs to the technical field of organic synthesis. In the present invention, first alkoxy-substituted benzyl halide, alkoxy-substituted benzaldehyde and a metal catalyst are subjected to oxidative addition and reduction elimination reactions to obtain alkoxy-substituted diphenylethanone; and then the alkoxy-substituted diphenylethanone and a metal catalyst are subjected to reduction, trans elimination and selective debenzylation reactions under a hydrogen atmosphere to obtain the resveratrol compound. In the preparation method of the present invention, the hydrogenation reduction, trans elimination and selective debenzylation reactions can be achieved just by a one-pot process, where the reaction directly obtains a trans olefin, thereby avoiding the formation of a isomer; and also the reaction selectively catalyzes debenzylation to eliminate Lewis acids from the source, and has the advantage of a high yield.

Abstract: The present invention discloses a core-shell structure supported tungsten composite catalyst and a preparation method and use thereof. Most of the existing synthesis methods of the main ring of quinolone drugs have the defects of many synthesis steps, cumbersome operation, large amount of three wastes, higher costs and the like. The present invention prepares a magnetic separable core-shell supported tungsten composite catalyst, WO3/SiO2/Fe3O4, by preparing Fe3O4 colloid and SiO2/Fe3O4 composite nano-particles. This magnetic separable core-shell supported tungsten composite catalyst, WO3/SiO2/Fe3O4, is used to catalyze and synthesize quinolone compounds. The present invention provides an efficient preparation method of quinolone compounds using a catalyst which can be recovered by magnetic separation and recycled.
