Abstract
This invention relates to a method for synthesizing (S)-3-methylheptanoic acid, which further expands the application scope of steroidal saponin degradation waste. The method of this invention conveniently synthesizes (S)-3-methylheptanoic acid from (R)-γ-methyl-δ-butyrate lactone obtained from the degradation of steroidal saponins. The method provided by this invention is simpler and more efficient than existing methods. It also helps to improve the utilization rate of steroidal saponin resources and reduce the generation of waste during their utilization.
