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.
