The Scope and Limitations of the Suzuki—Miyaura Cross-Coupling Reactions of 6- and 8-Substituted 1,2,3,4-Tetrahydroisoquinoline-3-carboxylates.

Abstract 6- and 8-Aryl-1,2,3,4-tetrahydroisoqinoline-3-carboxylates have been prepared by Suzuki–Miyaura cross-coupling reactions of the triflates or corresponding boronate esters. We have shown for the first time that a one-pot arylation of a triflate via the boronate ester can be achieved using an aryl chloride.
