Method for producing important steroid hormone dexamethasone methyl tetraenes intermediate
The invention discloses a method for producing an important steroid hormone dexamethasone methyl tetraenes (5ST) intermediate, which comprises the following steps of: dissolving a methyl dehydrate into an organic solvent, adding a reducing agent into the solution at the temperature of between 5 DEG C below zero and 20 DEG C, and performing one-step reaction to obtain methyl tetraenes with less than 0.8 percent of single impurity, wherein the reducing agent is a mixed reducing agent of 1 to 15 weight parts of chromium trichloride and 0.2 to 8 weight parts of zinc powder. The method for producing the 5ST shortens the reduction reaction into one-step reaction from three-step reaction so as to save the reaction time and facilitate the operation. The method reduces the consumption of chemical raw materials and dangerous goods, reduces the environmental pollution, and reflects the environment-friendly idea of green chemistry.
