The three-component reactions of aldehydes, electron deficient alkynes and ureas/thioureas have been smoothly performed to yield a class of unprecedented 3,4-dihydropyrimidinones and thiones (DHPMs). The reactions are initiated by the key transformation of an enamine-type activation involving the addition of a secondary amine to an alkyne, which enables the(More)
The three-component reactions of enals, electron-deficient alkynes, and hydroxyl-functionalized primary amines for the highly diastereoselective construction of dihydro-3H-benzo[4,5]oxazolo[3,2-a]pyridines, hexahydropyrido[2,1-b][1,3]oxazines, and tetrahydro-2H-oxazolo[3,2-a]pyridines have been achieved. Domino formation of one C-C, two C-N, and one C-O(More)
