We report the development of a Pd(II)/(±)-MeO-SOX/2,5-dimethylbenzoquinone system that enables unprecedented access to anti-1,3 amino alcohol motifs in good yields (33 substrates, avg. 66% isolated yield, >20:1 dr) and high selectivities (avg. 10:1 dr). Switching ligands to (±)-CF3-SOX with the use of a less bulky quinone oxidant, the kinetic syn-1,3 amino alcohol motif can be accessed in comparable yields and selectivities. Advantages of the stereodivergent nature of this reaction are seen in the synthesis of anti- and syn-1,3 amino alcohol vitamin D3 analogue intermediates in half the steps and higher overall yield relative to previous routes. Additionally, all eight possible stereoisomers of a chiral diamino alcohol core are generated from two amino acids. Mechanistic studies reveal that the anti-isomer is furnished through concurrent Pd(II)(SOX) catalyzed C-H amination and Pd(0)(SOX) catalyzed isomerization cycles.
