optimal reagent in terms of stability and synthetic efficiency. It combines sufficient nucleophilicity with good leaving group capacity of the resulting amide moiety under both basic and acidic conditions. To demonstrate the practical utility of this reagent, an efficient two-step synthesis of the potent opioid carfentanil is presented.
据报道2-异氰基吡啶是用于多组分化学的新型可转化异氰酸酯。对该类别的12位代表进行的比较显示,就稳定性和合成效率而言,2-溴-6-异氰基吡啶是最佳试剂。它在碱性和酸性条件下都具有足够的亲核性和所得酰胺部分的良好离去基团能力。为了证明该试剂的实用性,提出了有效的两步有效合成有效的阿片样物质芬太尼。
