Optimization of the palladium(II)-catalyzed oxidative cyclization of N,N-diarylamines opens up the way to an efficient synthesis of 2-oxygenated and 2,7-dioxygenated carbazole alkaloids including 2-methoxy-3-methylcarbazole, glycosinine, clausine L, mukonidine, and clausine V.
钯 (II) 催化的 N,N-二芳胺氧化环化的优化为有效合成 2-氧化和 2,7-双氧化
咔唑生物碱(包括 2-甲氧基-
3-甲基咔唑、糖苷、clausine L)开辟了道路、mukonidine 和 clausine V。
