A novel cascade annulation of 1,7-diynes with water has been developed for the synthesis of furo[3,4-c]quinolin-4(5H)-one skeletons with high atom- and step-economy. The transformation was enabled by a palladium catalyst in the presence of copper salt as

The invention discloses a synthesis method of furan[3,4-c]quinoline/furan[3,4-c]coumarin compound. The synthesis method comprises the following steps of: adding a compound shown in a formula I, a palladium catalyst, a copper catalyst, water and an organic solvent into a Schlenk sealed-tube reactor, stirring for reaction at the temperature of 80-120 DEG C under the atmosphere of oxygen, and after TLC and/or GC-MS detection for complete reaction, carrying out aftertreatment to obtain a target product shown in a formula II. The synthesis method disclosed by the invention has the advantages of moderate reaction condition, simple operation and wide reaction-substrate application range, and the route is applicable to production of two types of different compounds such as furan[3,4-c]quinoline/furan[3,4-c]coumarin compounds.
