• Direct Cross-Coupling Reaction of Simple Alkenes with Acrylates Catalyzed by Palladium Catalyst.

  Authors: Yun-He Xu, Jun Lu, Teck-Peng Loh

  Journal of the American Chemical Society. 02/2009;

  An efficient methodology for oxidative cross-coupling reaction of olefins with acrylates catalyzed by palladium(II) was developed. The corresponding dienoates were obtained in moderate to good yields.

• Enantioselective allylation of ketones catalyzed by chiral In(III)-PYBOX complexes.

  In the presence of 20 mol% of chiral catalytic complex prepared from In(OTf)3 and chiral PYBOX, allyltributylstannane reacted with achiral ketones to afford the corresponding homoallylic alcohols inIn the presence of 20 mol% of chiral catalytic complex prepared from In(OTf)3 and chiral PYBOX, allyltributylstannane reacted with achiral ketones to afford the corresponding homoallylic alcohols in moderate to high enantioselectivities (54-95% ee), which constitutes the first example of enantioselective allylation of ketones catalyzed by the chiral In(III)-PYBOX complex.

• Enantioselective allylation of aldehydes catalyzed by chiral indium(III) complexes immobilized in ionic liquids.

  Authors: Jun Lu, Shun-Jun Ji, Teck-Peng Loh

  Chemical communications (Cambridge, England). 06/2005;

  In the presence of chiral catalytic complexes prepared from In(OTf)3 and chiral PYBOX ligands, allytributylstannane reacted with aldehydes in ionic liquids to afford the corresponding homoallylicIn the presence of chiral catalytic complexes prepared from In(OTf)3 and chiral PYBOX ligands, allytributylstannane reacted with aldehydes in ionic liquids to afford the corresponding homoallylic alcohols in high enantioselectivities (86-94% ee) and good yields (68-89%); the chiral catalysts immobilized in ionic liquids could be reused with comparable enantioselectivities and yields.

• Enantioselective synthesis of homoallylic alcohols via a chiral In(III)-PYBOX complex.

  In the presence of 20 mol% of a chiral catalytic complex prepared from In(OTf)(3) and chiral PYBOX, allyltributylstannane reacted with aldehydes to afford the corresponding homoallylic alcohols inIn the presence of 20 mol% of a chiral catalytic complex prepared from In(OTf)(3) and chiral PYBOX, allyltributylstannane reacted with aldehydes to afford the corresponding homoallylic alcohols in moderate to high enantioselectivities (60-93% ee).

• Highly enantioselective allylation of aldehydes catalyzed by indium(III)-PYBOX complex.

  A chiral indium(III)-PYBOX complex prepared from indium triflate and chiral PYBOX has been discovered to effect high enantioselectivities in the addition of allyltributyl stannane to aldehydes. TheA chiral indium(III)-PYBOX complex prepared from indium triflate and chiral PYBOX has been discovered to effect high enantioselectivities in the addition of allyltributyl stannane to aldehydes. The allylation of a variety of aromatic, alpha,beta-unsaturated, and aliphatic aldehydes resulted in good yields and high enantioselectivities (up to 94% ee).
