Kinetic resolution of racemates under chiral catalysis: connecting the dots [PDF]
, 2012 The current theory of the titled phenomenon is apparently based on an inconsistent use of concentration units, as employed in the derivation of the fundamental equations. Thus, manifestly, whilst the relation between extent of conversion and e.e.

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.
