Abstract
The enantioselective [2,3]-Wittig rearrangement of cinnamyloxycyclopentanone derivatives was performed in the presence of a Cinchona-based primary amine. The described method provides synthetically valuable α-hydroxy ketones with quaternary stereogenic centers in excellent enantiomeric purities. Relying on the X-ray crystal structure of the product and the DFT calculations, we propose that the rearrangement is promoted by an intramolecular hydrogen bond between the substrate and the catalyst.

Abstract
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.
