Fu, Xiaoping; Qi, Qingqing; Xu, Shiqing; Negishi, Ei-ichi published an article in 2021. The article was titled ãChemo- and Stereoselective Dearomative Coupling of Indoles and Bielectrophilic β-Imino Boronic Esters via Imine-Induced 1,2-Boronate Migrationã? and you may find the article in Organic Letters.Name: Bis[(pinacolato)boryl]methane The information in the text is summarized as follows:
A new imine-induced 1,2-boronate migration was developed for achieving chemo- and stereoselective dearomative coupling of C3-substituted indoles and bielectrophilic β-imino boronic esters, providing rapid access to complex chiral indoline boronic esters with four stereocenters including an all-C quaternary stereocenter and a tertiary α-aminoboronic ester. By contrast, coupling of indoles without C3 substitution and β-imino boronic esters provided tetrahydro-1H-pyrido[4,3-b]indoles via imine-induced 1,2-boronate migration followed by deborylative rearomatization. In the experiment, the researchers used many compounds, for example, Bis[(pinacolato)boryl]methane(cas: 78782-17-9Name: Bis[(pinacolato)boryl]methane)
Bis[(pinacolato)boryl]methane(cas: 78782-17-9) belongs to organoboron compounds. Organoboron compounds have been a cornerstone of synthetic transformations for decades. Areas such as boron-containing catalysts, metalate chemistry, photoredox methods, and boryl anions have brought significant new developments in understanding and provided new reactivity upon.Name: Bis[(pinacolato)boryl]methane
