The invention relates to a preparation method for oxo-propenylmorpholine, which includes the steps of: performing an aminolysis reaction with polylactic acid and morpholine as raw materials; and then performing an elimination reaction under the effect of a catalyst to produce the oxo-propenylmorpholine, wherein in the aminolysis reaction, reaction temperature is 50-180 DEG C, reaction time is 1-24 h and reaction pressure is 1-5 atm; the molecular weight of the polylactic acid is 500-100000; and the molar ratio of the polylactic acid to morpholine is 1:1-2. In the method, the polylactic acid and morpholine are used as raw materials, so that the method is beneficial to recovery of the polylactic acid and reduces material cost. The method is high in yield and the product is easy to purify. The method is less in reaction steps and simple in operation and is free of generation of an acidic gas, HCl, during the reactions, so that corrosion on reaction equipment is avoided.
Enantioselective hydrogenation of α-ketoamides over Pt/A12O3 modified by cinchona alkaloids
