| titleOfInvention | Novel chemical total synthesis preparation method for coronalon |
| abstract | The invention discloses a novel chemical total synthesis preparation method for coronalon. The method comprises the following steps of: reacting ethyl benzene with butanedioic anhydride to generate 4-(4-ethyl benzene)-4-carbonyl-butyric acid; reducing the 4-(4-ethyl benzene)-4-carbonyl-butyric acid with a hydrazine hydrate to obtain 4-(4-ethyl benzene)-butyric acid; performing dehydration and ring concentration on the 4-(4-ethyl benzene)-butyric acid to form 7-ethyl-3,4-dihydronaphthalenone; reducing and dehydrating the 7-ethyl-3,4-dihydronaphthalenone to generate 7-ethyl-3,4-dihydronaphthalene; performing oxidation-induced double bond loop opening on the 7-ethyl-3,4-dihydronaphthalenone to obtain 2-(2-carboxyl ethyl)-5-ethyl-benzoic acid; and dehydrating and cyclizing the 2-(2-carboxyl ethyl)-5-ethyl-benzoic acid to obtain 6-ethyl-4-carboxyl-indenone; and condensing the 6-ethyl-4-carboxyl-indenone with isoleucine methyl ester hydrochloride to generate molecular coronalon serving as a target product. The novel chemical total synthesis preparation method for coronalon disclosed by the invention is more economical and effectively, and conditions are created for promoting the practicability of coronalon serving as an ideal inductive agent for plant potential high-value active ingredients. |
