Zhang, Jitan published the artcilePalladium-catalyzed Atroposelective Interannular C-H Arylation of Biaryl Aldehydes with Aryl Iodides Enabled by a Transient Directing Group Strategy, Application of 4-Chloro-2-methylphenylboronic acid, the publication is Advanced Synthesis & Catalysis (2022), 364(20), 3589-3599, database is CAplus.
A concise synthesis of axially chiral biaryl aldehydes through Pd/amino acid-catalyzed atroposelective interannular C-H arylation of biaryl aldehydes with aryl iodides is developed. This reaction proceeds smoothly involving excellent enantiocontrol and accomplishes with good tolerance of functional groups. Moreover, the readily accessible scale-up synthesis and further transformation of products has highlighted the potential utility of this asym. catalytic protocol.
