2,2-二甲基-1,3-二恶烷-4,6-二酮(米氏酸)广泛用于有机合成,特别是对于多种CC键形成,因为它具有足够的酸性 (pKa 4.83) 和空间刚性。在离子液体中,醛和米氏酸之间的克内文纳格尔缩合反应加速发生。
Usually used in the synthesis of macrocyclic β-keto lactone,4-pyridyl-substituted heterocycles,2-substituted indoles, isofraxidin.
2,2-Dimethyl-1,3-dioxane-4,6-dione (Meldrum′s acid) is widely used in organic synthesis, especially for multiple C-C bond formations due to its adequate acidity (pKa 4.83) and steric rigidity. Knoevenagel condensation reaction between aldehydes and Meldrum′s acid are accelerated in ionic liquids.
Usually used in the synthesis of macrocyclic β-keto lactone,4-pyridyl-substituted heterocycles,2-substituted indoles, isofraxidin.
