-
, (2020/09/12)
The invention provides a preparation method of R-N-Boc-3-pyrrolidine acetic acid, which comprises the following steps: by using N-Boc-3-pyrrolidone and trimethyl phosphonyl acetate as raw materials, carrying out wittig reaction, asymmetric reduction hydrogenation reaction and hydrolysis reaction to obtain the R-N-Boc-3-pyrrolidine acetic acid. The preparation method starts from a low-price racemicmixture N-Boc-3-pyrrolidone, the reaction conditions are mild, use of dangerous materials is not needed, the reaction steps are few, the process is simple, the single product R-N-Boc-3-pyrrolidine acetic acid with a target chiral structure can be finally obtained, the product has high purity, an optical activity ee value of more than 99% and high yield, and industrial scale-up production is facilitated.
