  Divergent Reactivity in the Reaction of β-Oxodithioesters and Hydroxylamine: Access to β-Ketonitriles and Isoxazoles

  摘要：

  Starting from beta-oxodithioesters and hydroxylamine, two completely different transformations afford either beta-ketonitriles or isoxazoles with high chemoselectivity depending on the reaction conditions. The reaction of beta-oxodithioesters with hydroxylamine in EtOH at room temperature in daylight gave beta-ketonitriles in high yields. On the other hand, 3-methylthio-isoxazoles were efficiently obtained as the final products by heating the mixture of beta-oxodithioesters and hydroxylamine in HOAc at 90 degrees C.

  Novel 3-alkanoyl/aroyl/heteroaroyl-2H-chromene-2-thiones: Synthesis and evaluation of their antioxidant activities

  摘要：

  A facile, convenient and high yielding synthesis of a combinatorial library of 3-alkanoyl/aroyl/heteroaroyl-2H-chromene-2-thiones has been developed by the condensation of easily accessible beta-oxodithioesters and salicylaldehyde/substituted 2-hydroxybenzaldehydes under solvent-free conditions. The assessment of radical scavenging capacity of the compounds towards the stable free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) was measured and these compounds were found to scavenge DPPH free radical efficiently. Five selected compounds were able to protect curcumin from the attack of sulfur free radical generated by radiolysis of glutathione (GSH). The newly synthesized compounds exhibited profound antioxidant activities Five of them rendered comparatively high antioxidant capacity.

  A green, regioselective protocol for the synthesis of thiopyrano[2,3‐d]thiazole‐2‐thiones catalyzed by basic ionic liquid [bmIm]OH has been developed. The reaction proceeds smoothly under microwave irradiation, and high yields of the products are obtained in very short reaction times (5–11 min). The ionic liquid plays a dual solvent‐catalyst role.

  已经开发了一种绿色的区域选择性方案，用于在碱性离子液体[bmIm] OH催化下合成噻吩并[2,3 - d ]噻唑-2-硫酮。在微波辐射下，反应可顺利进行，并且在很短的反应时间（5-11分钟）内即可获得高产率的产物。离子液体起着双重溶剂催化剂的作用。
