Transition metals in organic synthesis, part 82.1 First total synthesis of methyl 6-methoxycarbazole-3-carboxylate, glycomaurrol, the anti-TB active micromeline, and the furo[2,3-c]carbazole alkaloid eustifoline-D

The palladium(0)-catalyzed animation followed by palladium(II)-catalyzed oxidative cyclization of the resulting diarylamine provides a short route to a series of 6-oxygenated carbazole alkaloids: glycozoline, 3-formyl-6- methoxycarbazole, methyl 6-methoxy

We present here a metal-free, visible-light- and triphenylphosphine-mediated intermolecular, reductive amination between nitroarenes and boronic acids at ambient temperature without any photocatalyst. Mechanistically, a slow reduction of nitroarenes to a nitroso and, finally, a nitrene intermediate occurs that leads to the amination product with concomitant 1,2-aryl/-alkyl migration from a boronate complex. A wide range of nitroarenes underwent C-N coupling with aryl-/alkylboronic acids providing high yields.
Preparation method of secondary aromatic amine
-
Paragraph 0022, (2021/03/31)
The invention provides a method for preparing secondary aromatic amine by performing a palladium-catalyzed C-N coupling reaction on (pseudo)aryl halide and (pseudo)heterocyclic aryl halide and primary(heterocyclic)aromatic amine. The method is characterized in that an alkali for promoting the reaction is an alkali metal carboxylate or an alkali metal bicarbonate.
