本文报道了一种高效的HCl·DMPU辅助的醛一锅法转化为腈。使用HCl·DMPU作为酸源以及非亲核碱构成了用于制备腈的环境温和的替代方案。我们的方案顺利进行,没有使用有毒试剂和金属催化剂。具有各种官能团的多种官能化芳香族、脂肪族和烯丙基醛以优异的定量产率成功转化为腈。该方法具有底物范围广、反应条件温和、可扩展性强等特点。
We report an efficient HCl•DMPU assisted one-pot conversion of aldehydes into nitriles. The use of HCl•DMPU as both an acidic source as well as a non-nucleophilic base constitutes an environmentally mild alternative for the preparation of nitriles. Our protocol proceeds smoothly without the use of toxic reagents and metal catalysts. Diverse functionalized aromatic, aliphatic and allylic aldehydes incorporating various functional groups were successfully converted to nitriles in excellent to quantitative yields. This protocol is characterized by a broad substrate scope, mild reaction conditions, and high scalability.
