A series of N‐substituted diazabicyclo derivatives were designed and synthesized based on the active subunit combination and structure–activity relationship theory. The compounds were prepared by levulinic acid or ester with diamine, then acylation with phenoxy acetyl chloride or acetoxy acetyl chloride. All the structures were characterized by IR, 1H NMR, 13C NMR, MS, and elemental analysis. The single
基于活性亚基组合和结构-活性关系理论,设计和合成了一系列N-取代的二氮杂双环衍生物。通过乙酰丙酸或与二胺的酯,然后用苯氧基乙酰氯或乙酰氧基乙酰氯酰化来制备化合物。通过IR,1 H NMR,13 C NMR,MS和元素分析对所有结构进行表征。化合物4a的单晶通过X射线晶体学测定。初步的生物分析表明,所有产品都可以在一定程度上保护大豆免受2,4-D丁酸酯所造成的伤害。

Based on reactions of 5-substituted 3H-furan-2-ones or 4-oxocarboxylic acids with 1,2-binucleophiles of aromatic and aliphatic series methods were developed for the synthesis of tricyclic structures containing a pyrrolidine fragment fused with imidazolidine or oxazolidine ring. The pathways of the reactions are considered. It was demonstrated that the nature of the substrate did not affect the reaction direction, but changed the scheme of the interaction. The structures of compounds obtained for the first time were proved using IR and (1)H NMR spectra.
