Abstract:The catalytic asymmetric construction of N−N atropisomeric biaryls remains a formidable challenge. Studies of them lag far behind studies of the more classical carbon‐carbon biaryl atropisomers, hampering meaningful development. Herein, the first palladium‐catalyzed enantioselective C−H activation of pyrroles for the synthesis of N−N atropisomers is presented. Structurally diverse indole‐pyrrole atropisomers possessing a chiral N−N axis were produced with good yields and high enantioselectivities by alkenylati… Show more
