N-苯氧基乙酰基-1,3-恶唑烷衍生物是通过以β-氨基醇,酮和苯氧基乙酰氯为原料的环化和酰化反应合成的。所有化合物均通过IR,1 H NMR,13 C NMR,ESI-MS和元素分析进行了表征。4a的构型由X射线晶体学确定。初步的生物学测试表明,所有产品都可以在一定程度上保护大豆免受2,4-D丁酸酯的伤害。

A series of N-[(p-methylphenyl)sulfonyl]-1,3-oxazolidine-3-carboxamide 4 was synthesized by cycloaddition and acylation reaction with alkamine, ketones, and p-methylbenzenesulfonyl isocyanate as the starting materials. The structures of all the compounds were characterized by IR, H-1 NMR, C-13 NMR, MS, and elemental analysis. The configuration of 4d was determined by X-ray crystallography. The preliminary biological test showed that all compounds could protect maize against injury caused by chlorsulfuron to certain extent. The sulfonylurea oxazolidines were possible acted as antagonists of sulfonylureas herbicides at target enzyme pocket site by docking analysis.
