Abstract
For the first time the rhodium-catalyzed 1,4-addition of organoboranes to hindered Baylis-Hillman adducts, trisubstituted alkenes, affording highly functionalized alkenes, via addition of the organoboranes and hydroxyelimination, is reported. Moreover, preliminary results have shown that, thanks to the use of a monosubstituted chiral diene ligand, enantio-enriched products were easily accessible, while chiral phosphane ligands were completely inappropriate in this reaction.
