Abstract: A tandem Cu(I)-catalyzed conjugate addition of Kharasch reagents/diastereoselective protonation of ( E)-α-trialkylsilyl-β-alkyl(aryl)-α,β-unsaturated esters afforded the saturated products with d.r. values of >20:1 favoring the anti-diastereomer in modest to excellent isolated yields. read more here.
