Palladium Catalyzed C?O Coupling of Amino Alcohols for the Synthesis of Aryl Ethers

Article abstract of DOI:10.1002/adsc.201901302

Amine containing aryl ethers are common pharmacophore motifs that continue to emerge from drug discovery efforts. As amino alcohols are readily available building blocks, practical methodologies for incorporating them into more complex structures are highly desirable. We report our efforts to explore the application of Pd-catalyzed C?O coupling methods to the arylation of 1,2- and 1,3-amino alcohols. We established general and reliable conditions, under which we explored the scope and limitations of the transformation. The insights gained have been valuable in employing this methodology within a fast-moving drug discovery environment, which we anticipate will be of general interest to the synthesis and catalysis communities.
