Synthesis of functionalized quinolines via Ugi and Pd-catalyzed intramolecular arylation reactions.

Abstract

Two types of quinoline scaffolds were constructed in a combinatorial format via the Ugi four-component reaction (U-4CR) and Pd-catalyzed intramolecular arylation reaction. The scope of this two-step synthetic sequence was examined from commercially available and synthetically accessible starting materials.
