-
Paragraph 0063-0068, (2020/11/22)
The invention discloses a synthetic method of N - substituted hydantoin compounds, which comprises the following steps: taking an acyl azide compound shown as a formula I and a glycine ethyl ester compound as shown in a formula II as a raw material, carrying out heating reaction under the presence of an additive to obtain N - substituted hydantoin compounds as shown in formula III. In the formula, R1 And R2 Independently selected from hydrocarbyl, substituted hydrocarbyl, aryl, substituted aryl or aralkyl; R2 Selected from hydrocarbyl or aryl; R3 Selected from a hydrogen atom and a hydrocarbyl group. To the synthesis method, the functionalized N - substituted hydantoin compounds can be efficiently synthesized, the synthesis steps are few, the conditions are mild, the operation is safe, the raw materials are nontoxic, cheap and easily available, and the synthesis method has the N - substituted hydantoin compounds with the nitrogen heterocyclic skeleton with novel structure, the yield can reach 92%, the purity is 99%, and industrial synthesis is easy.
