A silver catalyzed cyclization of acetylene amine was developed to synthesize 4,6-substituted pyrrolo[3,2-d]pyrimidine, a bioactive isosteric scaffold of purine. Starting from simple commercially available acetylenes and pyrimidines, the method was found to be compatible with wide chemical functionalities, leading to a series of pyrrolo[3,2-d]pyrimidines in 84–91% yields.
开发了银催化的乙炔胺环化反应,以合成4,6-取代的吡咯并[3,2- d ]嘧啶,一种嘌呤的生物活性等排骨架。从简单的市售乙炔和嘧啶开始,发现该方法与广泛的化学功能兼容,从而导致一系列吡咯并[3,2- d ]嘧啶,收率84-91%。
A One-Pot Synthesis of Highly Functionalized Purines
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
