A novel method for the synthesis of 1-aryl-1,2-dihydro-3H-naphtho[1,2-e][1,3]oxazin-3-one derivatives employing one-potthree-componentreaction of β-naphthol, aromatic aldehydes, and urea using a catalytic amount of guanidine hydrochloride under solvent-free thermal conditions is described. This method provides several advantages like clean and environmentally benign reaction, simple work-up procedure
β-一锅三组分反应合成1-芳基-1,2-二氢-3 H-萘[1,2- e ] [1,3]恶嗪-3-酮衍生物的新方法描述了在无溶剂的热条件下使用催化量的盐酸胍的萘酚,芳族醛和尿素。该方法具有许多优点,例如干净且对环境无害的反应,简单的后处理程序,低成本,易于分离的产品,而无需通过柱色谱法进一步纯化,较短的反应时间和高收率。
