Ultrasound-assisted one-pot green synthesis of new N- substituted-5-arylidene-thiazolidine-2,4-dione-isoxazoline derivatives using NaCl/Oxone/Na3PO4 in aqueous media
synthesis of novel N-thiazolidine-2,4-dione isoxazoline derivatives 5 from N-allyl-5-arylidenethiazolidine-2,4-diones 3 as dipolarophiles with arylnitrile oxides via 1,3-dipolar cycloaddition reaction. The corresponding N-allyl substituted dipolarophiles were prepared by one-pot method from thiazolidine-2,4-dione with aldehydes using Knoevenagel condensation followed by N-allylation of thiazolidine-2,4-dione
一种快速,绿色的方法,通过1,3-偶极环加成反应从N-烯丙基-5-芳基萘并噻唑烷-2,4-二酮3与芳基腈氧化物合成新型N-噻唑烷-2,4-二酮异恶唑啉衍生物5。相应Ñ -烯丙基取代dipolarophiles通过制备一锅法从噻唑烷-2,4-二酮使用Knoevenagel缩合的醛,接着Ñ噻唑烷-2,4-二酮在超声处理下的NaOH水溶液的-allylation。另外,异恶唑啉衍生物5通过廉价和温和的NaCl / Oxone / Na 3 PO 4作为氯离子源,氧化剂和/或催化剂在EtOH / H 2 O(v / v,2: 1)作为绿色溶剂。在较短的反应时间内以高收率提供所有合成产物,然后通过NMR,质谱和X射线晶体学分析确认其结构。

characterized by 1H NMR, 13C NMR and ESI-MS spectrometry. All compounds were screened for their α-glucosidase and α-amylaseinhibitoryactivities. In vitro biological investigations revealed that most of compounds were active against α-glucosidase with IC50 values in the range of 43.85 ± 1.06 to 380.10 ± 1.02 µM, and α-amylase with IC50 in the range of 18.19 ± 0.11 to 208.10 ± 1.80 µM.
