Ruffell, Katie published the artcileBismuth-Mediated α-Arylation of Acidic Diketones with ortho-Substituted Boronic Acids, Product Details of C7H8BClO2, the publication is Angewandte Chemie, International Edition (2022), 61(40), e202210840, database is CAplus and MEDLINE.
The Bi-mediated oxidative coupling of acidic diones and ortho-substituted arylboronic acids was reported. Starting from a bench-stable bismacycle precursor, a sequence of B-to-Bi transmetallation, oxidation and C-C bond formation furnished the arylated diones. Development of methodol. that tolerates both sensitive functionality and steric demand was supported by interrogation of key reactive intermediates. Application of this strategy to cyclic diones enables the concise synthesis of important agrochem. intermediates which were previously prepared using toxic Pb reagents. This methodol. also enabled the first ever arylation of fluoroalkyl diones which, upon condensation with hydrazine, providesd direct access to valuable fluoroalkyl pyrazoles.
