, p. 8981 - 8985 (2005)
The stereo- and chemoselectivity in the additions of four model α-substituted allylboronates to benzaldehyde was examined under the standard thermal (uncatalyzed) conditions and the novel Lewis and Br?nsted acid-catalyzed conditions. With either of Sc(OTf

We describe the kinetic resolution of α-silyl-substituted allylboronate esters via chiral phosphoric acid-catalyzed chemo-, diastereo- and enantioselective allylboration of aldehydes. This process provides two synthetically versatile enantioenriched compo

(Chemical Equation Presented) Two for the show: A copper(I)-catalyzed reaction forms boron-silicon bifunctional cyclopropane derivatives from γ-silylated allylic carbonates and a diboron species (see scheme). The reaction is highly enantioselective when a chiral bisphosphine ligand is used. The stereoelectronic effect of the silyl group induces unusual regioselectivity of the boryl-copper(I) addition across the C-C double bond.
