Highly substituted purines were synthesized in good to high yields through a one-pot straightforward metal-free scalable method, using the Traube synthesis adapted to Vilsmeier-type reagents. From 5-amino-4-chloropyrimidines, new 9-aryl-substituted chloropurines and intermediates for peptide nucleic acid synthesis were prepared. Variant procedures allowing a rapid synthesis of ribonucleosides and 7-benzylpurine
使用适合Vilsmeier型试剂的Traube合成,通过一锅简单,无金属的可扩展方法,可以高产量合成高取代的嘌呤。由5-氨基-4-氯嘧啶,制备新的9-芳基取代的氯嘌呤和用于肽核酸合成的中间体。还报道了允许从5-ami基-6-氨基嘧啶快速合成核糖核苷和7-苄基嘌呤的各种方法,以说明这种多功能工具箱的巨大潜力。该途径在核酸领域中对于直接和快速地获得各种新的8-烷基嘌呤核苷似乎是特别令人感兴趣的。
