An electrochemical synthesis of 2-aminobenzoxazoles from 2-aminophenols and isothiocyanates was successfully developed in a one-pot fashion. Using inexpensive and widely available NaI and NaCl co-operatively in catalytic amounts, our electrosynthesis approach provided various 2-aminobenzoxazole products in moderate to high yields in an open-flask type undivided cell without using any external supporting
以一锅法成功开发了由 2-氨基苯酚和异硫氰酸酯电化学合成 2-氨基苯并恶唑。我们的电合成方法以催化量合作使用廉价且广泛可用的 NaI 和 NaCl,在不使用任何外部支持电解质和碱的情况下,在开放式烧瓶型未分隔电池中以中等至高产率提供各种 2-氨基苯并恶唑产品。该协议可用于以中等产率从相应的 2-苯硫酚合成 2-氨基苯并噻唑。该协议有很多好处。它不含金属且具有高度可扩展性,并在温和条件下使用廉价的介质和乙醇/水作为环保溶剂。

In this contribution, we report the design, synthesis and cytotoxicity studies of a series of N-[3-(benzimidazol-2-yl-amino)phenyl]amine and N-[3-(benzoxazol-2-ylamino)phenyl]aminederivatives. In vitro cytotoxicity assay of 26 selected compounds was carried out at National Cancer Institute (NCI), USA. Out of them, compounds 10e (NSC D-762842/1) and 11s (NSC D-764942/1) have shown remarkable cytotoxicity
