  Short Access to 6-Substituted Pyrimidine Derivatives by the S_RN1 Mechanism. Synthesis of 6-Substituted Uracils through a One-Pot Procedure

  摘要：

  The synthesis of 6-substituted 2,4-dimethoxypyrimidines with different nucleophiles was accomplished with good to excellent yields (50-95%) through S(RN)1 reactions, starting from commercially available 6-chloro-2,4-dimethoxypyrimidine (1). Hydrolysis of these derivatives gave access to 6-substituted uracils with good yields and short times by the use of microwave irradiation. The preparation of uracils from 1 without the isolation of 2,4-dimethoxypyrimidine derivatives affords a rapid access to these compounds in good yields and excellent purity by avoiding an unnecessary step of purification.
