The direct reaction between carbamates and achiral allylic carbonates to form branched, conveniently protected primary allylic amines with high regioseiectivity and enantioselectivity Is reported. This process occurs without base or with 0.5 equiv K3PO4 In the presence of a metalacyclic iridium catalyst containing a labile ethylene ligand. The reactions of aryl-, heteroaryl-, and alkyl-substituted allylic carbonates with BocNH 2, FmocNH2, CbZNH2, TrocNH2, TeocNH2, and 2-oxazolidinone occur In good yields, with high selectivity for the branched isomer and high enantioselectivities (98% average ee).

Iridium is blind to C: Highly regio- and enantioselective, iridium-catalyzed N-allylations of indoles, which complement the more common reactivity of indoles as carbon nucleophiles, have been developed (see scheme). These reactions form highly enantioenri
