A variety of functionalized quinoxalines were prepared through the reaction of the substrates with TMPMgCl.LiCl in the presence of ZnCl2 followed by the reaction with electrophiles. We can consider that first the base TMPMgCl.LiCl reacts with heterocycle affording the organomagnesium intermediate and then a fast transmetalation with Zn occurs, leading to the quinoxalilzinc intermediate (4), which is more stable than organomagnesium intermediate (Scheme 2).
