- Method for synthesizing tetrahydro beta-carboline-1-one compound through palladium catalysis
-
The invention discloses a method for synthesizing a tetrahydro beta-carboline-1-one compound through palladium catalysis. According to the method, carbonic oxide is used as a carbonyl source; the carbonic oxide and a tryptamine type compound react at ordinary pressure for efficiently preparing the tetrahydro beta-carboline-1-one compound. The method has the advantages that the tetrahydro beta-carboline-1-one compound with great application prospects is effectively prepared by using the carbonic oxide at the ordinary pressure as the carbonyl source and using bivalent metal palladium as a catalyst. From the angle of production and economy, through being compared with high-pressure reaction, the method has the advantages that the reaction cost is greatly reduced through carbonic oxide gas at normal temperature, and the reaction operability is improved.
