Abstract

Abstract Indolylnitroethanes and their derivatives are key intermediates to many bioactive structures. Most approaches to access chiral indolylnitroethanes involve organocatalyzed or metal-catalyzed asymmetric Friedel–Crafts reaction of indoles with nitroalkenes. We have developed an efficient approach to optically pure α-aryl-3-indolylnitroethanes through rhodium-catalyzed asymmetric 1, 4-addition of arylboronic acids to indolylnitroalkenes. ...
