The Enantioselective Tsuji Allylation [PDF]
Journal of the American Chemical Society, 2004 The first catalytic enantioselective examples of the Tsuji allylation using enol carbonates and enol silanes are described. The products possess a quaternary stereogenic center and are useful building blocks for synthetic chemistry.

Solvent Induced Enantioselectivity Reversal in a Chiral Metal Organic Framework [PDF]
, 2020 Solvent induced enantioselectivity reversal is a rarely reported phenomenon in porous homochiral materials. Similar behaviour has been studied in chiral HPLC, where minor mobile phase modifications can induce elution order reversal.

NiH-Catalyzed Enantio- and Regioselective Hydroselenylation of Unactivated Alkenes. [PDF]
Adv Sci (Weinh)Nickel‐hydride‐catalyzed enantio‐ and regioselective hydroselenylation of unactivated alkenes provides access to chiral organoselenium compounds. Enantiodetermining Ni–H insertion followed by single‐electron diselenide activation generates selenyl radical.
