介绍了不对称1,3,5-三取代-1,2,4-三氮唑的三组分一锅法在组合化学中的实现。该过程是基于胺与羧酸的偶联以及随后与肼的环化。通过对试剂范围的初步评估,该方法在平行合成中的成功率为81%。结果表明,根据所提出的方法,可以产生超过十亿个化学空间的容易获取的(“真实”)化合物。对理化参数的分析表明,该文库包含大量的类药物成员和超过五项规则的成员。超过1000万的可及化合物符合最严格的类铅标准。此外,还可以生产1.95亿吨富含SP3的化合物。这使得所提出的方法成为药物化学中的一个有价值的工具。
An implementation of the three-component one-pot approach to unsymmetrical 1,3,5-trisubstituted-1,2,4-triazoles into combinatorial chemistry is described. The procedure is based on the coupling of amidines with carboxylic acids and subsequent cyclization with hydrazines. After the preliminary assessment of the reagent scope, the method had 81% success rate in parallel synthesis. It was shown that over a billion-sized chemical space of readily accessible (“REAL”) compounds may be generated based on the proposed methodology. Analysis of physico-chemical parameters shows that the library contains significant fractions of both drug-like and “beyond-rule-of-five” members. More than 10 million of accessible compounds meet the strictest lead-likeness criteria. Additionally, 195 Mln of sp3-enriched compounds can be produced. This makes the proposed approach a valuable tool in medicinal chemistry.
