Synthesis of 2-Aminophenols and Heterocycles by Ru-Catalyzed C–H Mono- and Dihydroxylation
摘要:
A novel and efficient synthesis of 2-aminophenols, 2-aminobenzene-1,3-diols, and heterocycles through Ru-catalyzed C-H mono- and dihydroxylation of anilides has been developed with a new directing group strategy. The reaction demonstrates excellent reactivity, regioselectivity, good functional group tolerance, and high yields.

Mixing <i>O</i>-Containing and <i>N</i>-Containing Directing Groups for C–H Activation: A Strategy for the Synthesis of Highly Functionalized 2,2′-Biaryls
N-containing directing groups has been developed for the synthesis of 2,2′-biaryl via Pd-mediated C–Hbond activation and oxidative coupling. This new transformation may proceed through a mechanism involving Pd(II) and Pd(IV) intermediates. We found the use of PTSA and HFIP to be critical for the reaction and suggest that these reagents could serve as efficient ligands for this C–Cbond formation. This
