One-pot synthesis of 3,5-disubstituted 1,2,4-oxadiazoles from carboxylic acids and nitriles was optimized to parallel chemistry. The method was validated on a 141 member library; the desired products were recovered with a high success rate and in moderate yields. Practical application of the approach was demonstrated in the synthesis of bioactive compound pifexole and agonists of free fatty acid receptor 1. A library of 4 948 100 synthesizable drug-like 3,5-disubstituted 1,2,4-oxadiazoles was enumerated based on the method and available validated reagents.
将由羧酸和腈类化合物一锅法合成3,5-二取代-1,2,4-恶二唑的方法优化为平行化学方法。该方法在一个包含141个成员的文库上得到验证；目标产物的回收率很高，产率适中。该方法在生物活性化合物匹非克索和游离脂肪酸受体1激动剂的合成中得到了实际应用。基于该方法和可用的经过验证的试剂，列举了一个包含4948100种可合成的类药物3,5-二取代-1,2,4-恶二唑的文库。
