摘要：
A highly enantioselective cascade reaction of benzotriazoles with nitroolefin-containing enonates catalyzed by a base/acid bifunctional organocatalyst has been developed. This cascade sequence affords efficient access to densely functionalized chiral chromans with a quaternary stereogenic center in high yield (up to 91%) with excellent enantioselectivity (up to 96% ee) and diastereoselectivity (up to 96:4 dr). The reaction itself features simple experimental procedures under benign conditions and is completely at...
