DOI: 10.1039/c7gc03812g
Abstract: An efficient and green domino approach for the synthesis of 5,6,7,8-tetrahydropyrido[2,3-d]pyrimidin-4(3H)-one derivatives using a recoverable carbonaceous material as a catalyst has been established. The new domino reaction was conducted by reacting the readily available and… read more here.
