Non-metal catalytic method for preparing 1,3-diketone compounds based on acetyenic ketone

The invention discloses a non-metal catalytic method for preparing 1,3-diketone compounds based on acetyenic ketone. The preparation method is a stepwise method or a one-pot method. The stepwise method comprises the following steps: mixing an acetyenic ketone compound I, a nitrogen-containing aromatic compound II and a No.1 base for a reaction, performing separation and purification to obtain an intermediate product, mixing the intermediate product and a No.2 base for a reaction, and performing separation and purification to obtain the product; and the one-pot method comprises the following steps: firstly mixing an acetyenic ketone compound I and a nitrogen-containing aromatic compound II, adding a No.1 base, performing a reaction for a period of time, adding a No.2 base, continuing a reaction for a period of time, and finally performing separation and purification to obtain the product. The method provided by the invention has mild reaction conditions, simple operation and a higher yield, wherein the yield is generally 80% or more, and the method has greater practical application value in drug synthesis.
