Abstract We report herein an efficient and eco-friendly method for a one-pot sequential synthesis of quinazolin-8-ol derivatives. A variety of boronic acids were used for Suzuki–Miyaura coupling with commercially available SiliaCat ® DPP-Pd heterogeneous catalyst. Use of this catalyst ensures minimal leaching of palladium in the product and alleviates the need of further purification. The reaction

生物。多种
硼酸用于 Suzuki-Miyaura 与市售 SiliaCat®
DPP-Pd 多相催化剂的偶联。使用这种催化剂可确保最大限度地减少产品中
钯的浸出,并减少进一步纯化的需要。四个合成步骤中使用的反应条件经过优化,可以在不需要首先分离三个中间体的情况下,将它们分离出来,以建立高效且环保的一锅法合成。图形概要
