Synthesis and Formylation of Substituted 2-Spiropyrimidin-4-ones and Related Compounds

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

Treatment of cyclohexanone-2-carboxamide with cyclic ketones provides oxazine derivatives while refluxing in toluene with ammonium acetate and cyclic ketones yields substituted 2-spiropyrimidin-4-ones. Depending on the ratio of reactants, the oxazines and substituted 2-spiropyrimidin-4-ones under Vilsmeier-Haack conditions undergo formylation or an electrophilic rearrangement.
