摘要

Abstract Diimmonium salt (5) reacts with guanidines (6) and o-methylisoureas (7) affording 2- amino-4, 5-dimorpholinoimidazolines (9). 1-Aryl-2-amino-4, 5-dimorpholinoimidazolines lose the amino functionality under mild acidic conditions with formation of 2-amino-5- morpholinoimidazole derivatives (10) whereas 1-acyl derivatives undergo under the same conditions a ring expansion process leading to pyrimidine derivatives (13).
