, p. 2987 - 2990 (2002)
Highly syn-(87-98%) diastereoselective addition of (E)-cinnamyl(tributyl)tin to α-keto esters under the influence of titanium tetrachloride, leading to the isolation of pure alkyl syn-2-aryl-2-hydroxy-3-phenylpent-4-enoates in 50-80% yields, is described.
Highly enantioselective allylation of α-ketoesters catalyzed by N,N′-dioxide-in(III) complexes

, p. 8478 - 8483 (2008/02/13)
(Chemical Equation Presented) An efficient asymmetric allylation of α-ketoesters was catalyzed by the N,N′-dioxide-In(III) complex in excellent yields (up to 99%) and high enantioselectivities (up to 94% ee) for a variety of substrates under mild reaction
Benzhydryldimethylsilyl allylic silanes: Syntheses and applications to [3 + 2] annulation reactions
Peng, Zhi-Hui,Woerpel
, p. 1379 - 1381 (2007/10/03)
(Matrix Presented) A new silyl group, the benzhydryldimethylsilyl group, has been developed that is easily synthesized and that undergoes facile oxidation. The [3 + 2] annulation reactions of allylic silanes with this silyl group provide a variety of high
