GRAPHICAL ABSTRACT ABSTRACT Ten novel N-phosphoryl amino acids β-sitosterol esters were synthesized by coupling the N-phosphoryl amino acids with β-sitosterol under microwave irradiation, and their structures were elucidated by IR, NMR, and HR MS. Various reaction conditions including the catalyst, solvent, temperature and time were investigated. Under the optimal conditions, the reaction was finished in
图形摘要 摘要 通过在微波辐射下将 N-磷酰氨基酸与 β-谷甾醇偶联合成了 10 种新型 N-磷酰氨基酸 β-谷甾醇酯,并通过 IR、NMR 和 HR MS 阐明了它们的结构。研究了各种反应条件,包括催化剂、溶剂、温度和时间。在最佳条件下,在室温下使用 DCC/DMAP 作为催化剂体系,反应在 20 分钟内完成,产率为 60-87%。
