Molybdate sulfuric acid (MSA) has been found as an efficient and reusable solid acid catalyst for the synthesis of new 2,3,4,5-tetrasubstituted pyrroles via a novel [2+2+1] strategy. Thus, one-pot three-component reaction of benzoin derivatives, 1,3-dicarbonyls, and ammonium acetate afforded the desired products in high yield under solvent-free conditions.
钼酸硫酸(MSA)已被发现是一种有效且可重复使用的固体酸催化剂,可通过新颖的[2 + 2 + 1]策略合成新的2,3,4,5-四取代的吡咯。因此,安息香衍生物,1,3-二羰基化合物和乙酸铵的一锅三组分反应在无溶剂条件下以高收率提供了所需的产物。
