| titleOfInvention | Synthetic method of diethyl naphthylmethyl-tetrahydrofurfurylmalonate |
| abstract | The invention discloses a method for synthesizing menaphthyl tetrahydrofuryl ethyl malonate as shown in a formula (I). The synthesis method is as follows: sodium alkoxide is added into a 2-methyl tetrahydrofuran solution of the menaphthyl tetrahydrofuryl ethyl malonate as shown in a formula (II) in batch at a temperature of between 20 and 45 DEG C; after addition, the mixture is heated and refluxed for 0.5 to 2 hours, and 1-methylnaphthalene halide as shown in a formula (III) is slowly dripped into the mixture at a temperature of between 80 and 100 DEG C; the mixture is subjected to reflux reaction for 0.5 to 2 hours; and the menaphthyl tetrahydrofuryl ethyl malonate is obtained after after-treatment of a reaction liquid. Compared with the prior art, the method has the advantages that the menaphthyl tetrahydrofuryl ethyl malonate adopts a green solvent, namely 2-methyl tetrahydrofuran as a reaction solvent and is also directly taken as an extracting solvent; and the method has high yield of reaction products and high recovery rate of the solvent, is environment-friendly, and has good industrial application prospect. |
