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.

A method for the synthesis of difficult-to-access amides was developed through the coupling of stericallyhindered carboxylic acids and electron deficient amines via SO2F2-mediated dehydration. The method feathers with broad substrate scope, mild conditions, excellent functional group compatibility and high yields.
