Abstract
AbstractThe Iridium‐catalyzed asymmetric hydrogenation of cyclic sulfamidate imines was successfully developed with N‐methylated ZhaoPhos L2 as the ligand. A variety of chiral cyclic sulfamidates were obtained with excellent results (up to 99% yield, 99% ee). Furthermore, this asymmetric hydrogenation can be employed as the key reaction step to prepare the important intermediates in organic synthesis.magnified image
