  Selective Synthesis of 7-Substituted Purines via 7,8-Dihydropurines

  摘要：

  A simple and efficient protocol for the preparation of 7-substituted purines is described. 6- and 2,6-Dihalopurines were N-9-tritylated and then transformed to 7,8-dihydropurines by DIBAL-H. Subsequent N-7-alkylation followed by N-9-trityl deprotection with trifluoroacetic acid was accompanied by spontaneous reoxidation, which led to the 7-substituted purines at 55-88% overall isolated yields.
