Direct C–H borylation and C–H arylation of pyrrolo[2,3-d]pyrimidines: synthesis of 6,8-disubstituted 7-deazapurines†
Abstract
Novel direct C–H borylations of 7-deazapurines to position 8 by B2pin2 under Ir catalysis were followed by Suzuki cross-couplings with aryl halides and other functional group transformations to give diverse 8-substituted 7-deazaadenines.
