超声促进CuSO4/NaAsc水相中高效催化合成N-苯磺酰基苯乙酰胺及其抑制种子萌发的研究

doi:10.6023/cjoc202201010

摘要/Abstract

为了高效、高收率地获得新型N-苯磺酰基苯乙酰胺脱落酸类似物, 取代苯乙炔和苯磺酰叠氮为起始原料, 水相中超声辐射下经廉价的CuSO₄/NaAsc (NaAsc为抗坏血酸钠)催化获得32个目标化合物. 该方法操作简单、收率高(86%~95%)、溶剂环保. 种子萌发实验结果表明, 25和50 µmol/L目标化合物处理后大豆种子发芽明显受阻, 其中22个目标化合物处理后抑制率为100%, 活性优于脱落酸(ABA). 该结果有利于快速地合成具有高抑制萌发活性的新型脱落酸类似物

关键词: 硫酸铜/抗坏血酸钠, 超声辐射, N-苯磺酰基苯乙酰胺, 脱落酸类似物, 抑制种子萌发

Substituted phenylene and benzenesulfonyl-azides were used as starting materials to obtain N-benzensulfonyl phenylacetamide abscisic mimics (PACs). 32 target compounds were efficiently and quickly obtained via cheap combination of CuSO₄/NaAsc (NaAsc, sodium ascorbate) catalysis under ultrasonic radiation in water (86%~95%). Furthermore, 22 target compounds could overwhelmingly inhibit soybean seed germination at the concentration of 50 and 25 µml/L. These results are benefit to discovering novel seed germination inhibitor agents.

Key words: CuSO₄/NaAsc, ultrasonic radiation, N-benzensulfonyl phenylacetamide, abscisic acid mimics, inhibition seed germination
