  An environmentally friendly, one-pot, three-component ZnS nanoparticle-mediated synthesis of biologically important spirooxindole derivatives in water under ultrasonic irradiation is described herein. ZnS nanoparticles were synthesized by aqueous chemical method. The advantages of this method lies in its simplicity, cost effectiveness, environment friendliness, easier scaling up for large scale synthesis without using high pressure, temperature and toxic chemicals. Greenness of the process was well instituted as water was exploited both as reaction media as well as medium for synthesis of catalyst (ZnS nanoparticles). The particle size was determined by transmission electron microscopy (TEM) and XRD. Compared with other methods for synthesis of spirooxindole derivatives, satisfactory results were obtained with high yields, short reaction time, with simple experimental procedure. After reaction course, the ZnS NPs can be recycled and reused without any apparent loss of activity.

  本文介绍了一种在超声波辐照下，以 ZnS 纳米粒子为介导，在水中合成具有重要生物活性的螺吲哚衍生物的环保型一锅三组份合成方法。ZnS 纳米粒子采用水化学方法合成。这种方法的优点在于简单、成本效益高、环境友好，而且无需使用高压、高温和有毒化学品，更容易进行大规模合成。由于水既可用作反应介质，也可用作合成催化剂（ZnS 纳米粒子）的介质，因此该工艺绿色环保。粒度由透射电子显微镜（TEM）和 XRD 确定。与其他合成螺吲哚衍生物的方法相比，该方法产率高、反应时间短、实验过程简单，取得了令人满意的结果。反应过程结束后，ZnS NPs 可回收再利用，且没有明显的活性损失。

  Ultrasound promoted, cerium ammonium nitrate catalyzed sustainable synthesis of spiro[indoline3,4'-pyrano[2,3-c]pyrazole] derivatives (4a-l) is reported herein. The synthesized compounds were screened for their antioxidant activities as free radical scavenging effect on diphenylpicryl hydrazine (DPPH center dot), 2,2'-azino-bis(3-ethylbenzthiazoline- 6-sulphonic acid) (ABTS(center dot+)) and nitric oxide (NO) radicals. The screened compounds showed potent scavenging activities against DPPH center dot, ABTS(center dot+) and NO radicals. In order to further extend on studies and to obtain a deep insight into structure activity relationship of this class of compounds, we designed N-substitution of indole moiety with the aim to study its antioxidant potential.
