Expedient Approach to Novel N-Unprotected Bicyclic Azapyrimidine and Pyridine Structures
摘要:
A direct route to novel bicyclic N-unprotected azapyrimidine structures including fused five-, six-, and seven-membered rings is described involving radical addition and cyclization of xanthates; this approach could be partially extended to pyridines.
