Abstract

The results presented herein illustrate the feasibility of two orthogonally reacting boron coupling reagents as a new control strategy in multicomponent-multicatalytic reaction [(MC)2R] chemistry. A process employing dichlorovinylpyrazine merging the rhodium-catalyzed hydroarylation with the Suzuki coupling has been discovered. Three new bonds are formed in a one-pot, one-step process efficiently providing highly substituted diaza-dihydrodibenzoxepine products.
