Selective construction of 2-substituted benzothiazoles from o-iodoaniline derivatives S8 and N-tosylhydrazone via a copper-promoted [3 + 1 + 1]-type cyclization reaction has been realized. In the protocol, the carbon atom on N-tosylhydrazone could be regulated to construct benzothiazole by changing the reaction system. Furthermore, the transformation has achieved the construction of multiple carbon-heteroatom
已经实现了通过铜促进的[3 +1 + 1]型环化反应,由邻碘苯胺衍生物S 8和N-甲苯磺酰zone选择性构建2-取代的苯并噻唑。在该方案中,可以通过改变反应体系来调节N-甲苯磺酰hydr上的碳原子以构建苯并噻唑。此外,该转化实现了多个碳-杂原子键的构建。
