One-step synthesis of ‘privileged medicinal scaffolds’, 2-amino-3,5-dicarbonitrile- 6-sulfanylpyridines, has been demonstrated via a multicomponent reaction of aldehydes, malononitrile, and thiols using silica nanoparticle (NP) as catalysts. The silica NP catalysts are very mild (nearly neutral in nature), effective, environmentally benign, and retain most of their activities after being reused for
通过使用二氧化硅纳米颗粒(NP)作为催化剂的醛,丙二腈和硫醇的多组分反应,已证明了“特权药物支架” 2-氨基-3,5-二甲腈-6-磺酰氨吡啶的一步合成。二氧化硅NP催化剂非常温和(本质上几乎是中性的),有效,对环境无害,并且在重复使用3次后仍保留了大部分活性。
