| titleOfInvention | Synthesis method of azetidine-3-formic acid |
| abstract | The invention relates to the field of organic synthesis, in particular to a method for synthesizing azetidine-3-formic acid, which comprises the steps of reacting 2, 2-dihydroxymethylmalonic acid-1, 3-diethyl ester with benzhydrylamine after the protection of methanesulfonyl chloride, and then decarboxylating and removing the protection of benzhydryl to obtain the final product azetidine-3-formic acid. The synthesis method takes 2, 2-dimethylolmalonic acid-1, 3-diethyl ester as a raw material, is cheap and easy to obtain, reduces the cost of the whole synthesis line by more than 30 percent compared with the cost of the original synthesis line, does not adopt a highly toxic substance sodium cyanide, and has great industrial production prospect. |
