The invention discloses a novel method for preparing chiral 3-morpholine methanol and 3-morpholine formic acid compounds. The method comprises the following steps: taking chiral serine as an initial material to obtain a serine ester (III) from a catalyst by esterification; reacting with halogen acetyl halide under an alkaline condition to obtain a compound (IV); obtaining a compound (V) by hydroxyl protection; adding a reducing agent to restore the ester into alcohol (VI); carrying out cyclization under the alkaline condition to obtain a compound (VII); obtaining a target product chiral 3-morpholine methanol compound (I) by amide reduction, hydroxyl deprotection and N protection; obtaining a chiral 3-morpholine formic acid compound (II) by oxidation. The method has the advantages of being low in cost, friendly to environment, simple to operate, high in yield, high in product purity and the like, the used reagent is simple and safe, and an intermediate in the reaction of each step does not need to be further purified, so that the experiment operation is greatly simplified, the production cost is reduced, and the method is applicable to industrial production.
