Increasing research has focused on examining the similarity between pyridopyrimidines and pyrimido [2,3-d]pyrazines, also referred to as pteridines [1]. Significant antitumor activity against Walker muscular carcinosarcoma in rats has been demonstrated for 4-oxopyrido [2,3-d]pyrimidine (A) and 2,4-d

β¦ Synopsis
The synthesis of 4-amino-7-(8-D-ribofuranosyl)-furoC3.2-dlpyrimidine, a new Cnucleoside analog of adenosine. is described. It involves base-catalyzed cyclization of the 2-(ribofuranosyl)-t-cyan0 ethers 3 to afford the ribosyl-3-amino-2-cyanofurans 4a and 48. followed by a two step conversion into the desired furoI3.2-dlpyrimidine system.
