An efficient and convenient method for the synthesis of indol-3-yl benzo[b][1,6]- and benzo[c][2,7]naphthyridines via copper(II) triflate-catalyzed heteroannulation is reported. This method gives new analogues of indole containing benzonaphthyridines from easily accessible starting materials. This reaction proceeds under mild conditions.
报道了一种通过三氟甲磺酸铜(II)催化杂环化合成吲哚-3-基苯并[ b ] [1,6]-和苯并[ c ] [2,7]萘吡啶的有效简便方法。该方法从易于获得的起始原料中得到了含有吲哚的新吲哚类似物。该反应在温和的条件下进行。
