Microwave-Assisted Solvent-Free Synthesis of Highly Functionalized Pyrimidine Derivatives
摘要:
We here described an efficient method for the synthesis of a series of highly functionalized pyrimidines via the addition and condensation reaction of ketene dithioacetals with guanidine carbonate or amidine hydrochlorides by microwave irradiation under solvent‐free conditions in the absence of a catalyst, giving the products with good yields (79–98%).
