| titleOfInvention | Marine natural product Echinoclathrine A preparation method |
| abstract | The invention relates to a marine natural product Echinoclathrine A preparation method and belongs to the technical field of pharmaceutical chemicals. In order to solve the problems that the existing technology is simple and low in yield, the invention provides the marine natural product Echinoclathrine A preparation method. The preparation method comprises the following steps: with an acid application agent, 3-cl-2-aminophenol and n-butyryl chloride butanoyl chloride perform a substitution reaction in halogenated hydrocarbon to acquire an intermediate product; under the function of an alkaline reagent, with a palladium catalyst and a phosphorus compound, the intermediate product and 2-methyl pyridine boric acid have a reaction to acquire the final product Echinoclathrine A. The preparation method has the advantages of simple technology, and high product purity and yield. |
