Abstract The reaction of isomeric 2/3-bromomethylindoles containing masked aldehydic function with heteroarenes in the presence of Zn(OTf)2 as a catalyst in 1,2-DCE at room temperature led to the formation of benzo[b]-hetero annulated carbazoles.
摘要 在 Zn(OTf) 2作为催化剂存在下,在 1,2-DCE 中室温下,含有掩蔽醛官能团的异构 2/3-溴甲基吲哚与杂芳烃的反应导致苯并[ b ]-杂环化咔唑的形成。
A one pot synthesis of annulated carbazole analogs
A ZnBr2-mediated arylation of N-protected 2/3-bromomethylindoles containing an electron-deficient malonylidene unit with arenes at 80 degrees C led to the formation of arylated products, which on Unprecedented 1,5-sigmatropic rearrangement followed by electrocyclization and subsequent aromatization with loss of diethylmalonate furnished the corresponding annulated carbazoles in reasonable yields.
