Three-component synthesis of imidazo[1,2-c]pyrimidines using silica sulfuric acid (SSA)
摘要:
This letter describes a simple and efficient synthesis of 3-(cyclohexylamino)-7-hydroxy-2-arylimidazo[1,2-c]pyrimidin-5(6H)-one via a one-pot three-component reaction of cyclohexyl isocyanide, an aldehyde, and 4-amiopyrimidine-2,6-diol in the presence of a catalytic amount of SSA.
