Palladium-catalyzed cross-coupling reaction between dichlorotriazines and phenylboronate esters produced the mono-awlated triazines selectively and thus, the corresponding phenyltriazine derivatives could be assembled efficiently in moderate to good overall yields （50-80%）.
One-pot synthesis of substituted pyrano- and furano[3,2-c]quinoline derivatives from appropriately substituted anilines, substituted benzaldehydes and dienophiles via Povarov reaction catalyzed by HCl-ethanol were reported. Good to excellent yields with high diastereoselectivity were obtained in all entries tested.
