摘要

介绍了高水溶性配体7-磷酸-1,3,5-三氮杂-阿曼烷丁烷磺酸盐(PTABS)的合成及其催化应用。合成的PTABS配体与醋酸钯在室温下对6-氯-9-(β- d -核呋喃基)- 9h -嘌呤的胺化反应表现出良好的反应活性。该方案提供了一个优势比先前发表的程序胺化6-氯嘌呤核苷提供6- n取代腺苷类似物。通过合成一种以尿嘧啶为基础的抗糖尿病药物阿格列汀，证实了当前策略的有效性。©2018 by John Wiley &儿子,Inc。

Pd/PTABS: An Efficient Water-Soluble Catalytic System for the Amination of 6-Chloropurine Ribonucleoside and Synthesis of Alogliptin

The synthesis and catalytic applications of the highly water-soluble ligand 7-phospha-1,3,5-triaza-admantane butane sultonate (PTABS) has been described. The synthesized PTABS ligand along with palladium acetate exhibits excellent reactivity towards the amination reaction of 6-chloro-9-(β-D-ribofuranosyl)-9H-purine at ambient temperature. This protocol offers an advantage over the previously published procedures for the amination of 6-chloropurine nucleoside furnishing 6-N-substituted adenosine analogues. The validation of the present strategy has been demonstrated via synthesis of a uracil-based, anti-diabetic drug alogliptin. © 2018 by John Wiley & Sons, Inc.
