A Pd-catalyzed asymmetric allylic amination using aspartic acid derived P-chirogenic diaminophosphine oxides (DIAPHOXs) is described. Asymmetric allylic amination of both linear and cyclic substrates proceeded at room temperature to give the chiral allylic amines in 72-99% ee.
A Pd-catalyzedasymmetricallylicalkylation of 2-substituted cycloalkenyl carbonates using a chiral diaminophosphine oxide is described. Asymmetricallylic substitution of various cyclicsubstrates proceeded using 5 mol % of Pd catalyst, 10 mol % of (S,RP)-Ph-DIAPHOX 1, 10 mol % of LiOAc, and N,O-bis(trimethylsilyl)acetamide (BSA), to afford the corresponding products in excellent yields with up to
