Sequential Ir-Catalyzed Allylation/2-aza-Cope Rearrangement Strategy for the Construction of Chiral Homoallylic Amines?

Article abstract of DOI:10.1002/cjoc.202000065

Sequential Ir-catalyzed asymmetric allylation/2-aza-Cope rearrangement of arylidene aminomalonates with allylic carbonates was successfully developed, and a variety of enantioenriched homoallylic amine derivatives were obtained in high yields with good chirality transfer and excellent E/Z-geometry control (up to 99% yield, 96% ee). Compared with previous dual catalytic system established for this transformation, the current mono metal catalytic system provides a simpler and more practical protocol employing the readily available starting materials.
