Triflic Acid‐Catalyzed Chemo‐ and Site‐Selective C−H Bond Functionalization of Phenols With 1,3‐Dienes
摘要:
AbstractHerein, a Brønsted acid‐catalyzed C(sp2)−H functionalization of free phenols with 1,3‐dienes has been developed. In this transformation, triflic acid promoted C−H bond functionalization under mild conditions in a site‐selective manner.magnified image

2-dicarbofunctionalization of 1,3-dienes employing o-bromoaryl imines as a bis-electrophilic coupling partner. This method provides an entry to prepare disubstituted cis-indanes in high diastereo- and enantioselectivities under mild reaction conditions. The proposed reaction mechanism consists of enantioselective intermolecular migratory insertion and diastereoselective intramolecular allylation as the key
