Amino acid-promoted C–H alkylation with alkylboronic acids using a removable directing group†
Abstract
Palladium-catalyzed C–H alkylation reaction with alkylboronic acids has successfully been developed using a removable pyridyldiisopropylsilyl directing group. The amino acid played a crucial role as a ligand in the reaction. The alkylation protocol is also applicable to the coupling of C(sp3)–H bonds with alkylboronic acids.
