The invention discloses a
monoamine oxidase A inhibitor, which is obtained by using cheap
ruthenium carbon as a catalyst to catalyze the synthesis of
thioether at
room temperature, specifically: using the compound represented by formula (III) as the reaction
raw material, Ru / C as catalyst, NaIO 4 is an oxidant, water is a
solvent, and the reaction is carried out at
room temperature. After the reaction is completed, the reaction liquid is post-treated to obtain the
sulfone compound shown in formula (IV). The method of the invention uses water as a
solvent, oxidizes cheap
ruthenium carbon with
sodium periodate to generate
ruthenium tetroxide, and further oxidizes the
sulfide compound to synthesize the target product, and the preparation method is more efficient, quick,
environmentally friendly and mild. The prepared
monoamine oxidase A inhibitor has good
monoamine oxidase A inhibitory activity, can be used to prepare a
drug for inhibiting the activity of
monoamine oxidase A, and has broad application prospects in
drug development, in order to provide a more effective way for the treatment of related diseases.
