摘要：

A regioselective ytterbium-catalyzed annulation reaction between ethylglyoxalate, anilines and silylalkynes bearing selenyl- and telluryl-moieties for the formation of poly-substituted quinolones is described. A series of examples formed under mild conditions are presented, including a scaled-up reaction and a study on catalyst recyclability. (C) 2018 Elsevier Ltd. All rights reserved.
