The invention discloses divinyl diacyloxy amide organic synthetic intermediates and a preparation method thereof. The chemical structural formula is shown in the description, wherein substituent groups R1, R2, R3 and R4 are hydrogen, halogen, aryl, alkyl, nitryl or alkoxy, and the position, number and conjugation position of the substituent groups are not fixed. According to the synthesis method, an intermediate produced through a Passerini reaction of cinnamic acid derivatives, aryl ketoaldehyde derivatives and isocyanide derivatives reacts with acyl chloride under the catalytic action of a Bronsted acid catalyst to produce the divinyl diacyloxy amide organic synthetic intermediates. The divinyl diacyloxy amide organic synthetic intermediates are synthesized with a novel synthesis method which comprises few steps and is high in yield. The compounds contain multiple functional groups, have good molecular diversity and can be widely applied in the organic synthesis field such as mass preparation of complex organic molecules, synthesis of macrocyclic compounds, preparation of functional cyclic compounds and the like.
