Copper catalyzed tandem conjugated borylation–aldol reaction

We investigated the tandem conjugated borylation–aldol reaction catalyzed by copper complexes. After identification and optimisation of the catalytic system, the scope of the reaction was evaluated and the diastereoselectivity was studied on both linear and cyclic activated alkenes. Finally, the use of some selected borylated aldol adducts in two classical transformations was investigated.
