Method for synthesizing azetidine -3 - formic acid
-
Paragraph 0027-0028, (2021/10/02)
The invention relates to the field of organic synthesis and particularly relates to a synthetic method of azetidine-3-formic acid. The synthetic method comprises the following steps of adopting 2,2-bis(hydroxymethyl)malonic acid-1,3-diethyl ester to react with benzhydrylamine after protection of methylsulfonyl chloride, and then by decarboxylation and diphenylmethyl-removing protection, obtaininga final product, namely the azetidine-3-formic acid. The synthetic method has the advantages that the 2,2-bis(hydroxymethyl)malonic acid-1,3-diethyl ester is adopted as a raw material, and is cheap and easy to obtain; compared with the original synthesis route, the cost of the whole synthesis route is reduced by 30% or more, and a highly-toxic substance (sodium cyanide) is not adopted, so that theindustrial production prospect is great.
