Chemo- and Stereoselective Dearomative Coupling of Indoles and Bielectrophilic -Imino Boronic Esters via Imine-Induced 1,2-Boronate Migration. Academic Article uri icon


  • A new imine-induced 1,2-boronate migration has been developed for achieving chemo- and stereoselective dearomative coupling of C3-substituted indoles and bi-electrophilic -imino boronic esters, providing rapid access to complex chiral indoline boronic esters with four stereocenters including an all-carbon quaternary stereocenter and a tertiary -aminoboronic ester. In contrast, coupling of indoles without C3 substitution and -imino boronic esters provided tetrahydro-1H-pyrido[4,3-b]indoles via imine-induced 1,2-boronate migration followed by deborylative rearomatization.
