Paragraph 0015-0016, (2020/11/26)
The invention discloses a novel method for directly synthesizing oxazolidine -2 and 4 - diketone heterocyclic compounds from alkyne amide raw materials. The method has high catalytic reaction activity at 10% DEG C, N - methylpyrrolidone, dimethyl sulfoxide or N, N - dimethylformamide as a solvent, and is high in yield, wide in substrate application range and capable of synthesizing -2 oxazolidine 50 - 150 °C 4 - and 0.5 - 24h diketone heterocyclic compounds in a gram-scale manner; furthermore, the method has the advantages of low sensitivity -2 89 - 92%. to air, high chemical selectivity, easy separation and short reaction time of the product, and 4 - the like in the first time, and the method has the advantages of high yield.2 4.
