The development of enantioselective C-H macrocyclizations to efficiently access structurally diversified macrocycles is highly desirable,but remain a big challenge.Herein,we reported the first rhodium(Ⅲ)-catalyzed asymmetric intramolecular C-H macrocyclization,enabling the efficient synthesis of structurally diverse enantioenriched macrocycles.This robust enantioselective C-H macrocyclization has a broad functional group tolerance,excellent enantioselectivities(up to 98.5:1.5 e.r.)and a mild reaction con-dition,releasing CO2 as the single by-product.More significantly,the resulting unique enantioenriched 19-membered macrocycle 2f was found to demonstrate a potent in vitro anti-Zika virus(ZIKV)activity without obvious cytotoxicity.Further investigation revealed that the anti-ZIKV activity is presumably at-tributed to an autophagy inhibition in the early stage of viral infection by down-regulating the expression of autophagy related gene Atg12.
