The synthesis of aryl-hydrazones from aromatic aldehydes/ketones and hydrazides (semicarbazide, thiosemicarbazide and aminoguanidine) is described using aqueous medium (acid conditions) under ultrasound irradiation with short reaction times (20–30 min), the reactions occurring at room temperature and giving rise to good to excellent yields of the products, along with the diastereoselectivities. The
描述了使用水性介质(酸性条件)在短时间(20-30分钟)超声辐照下,由芳族醛/酮和酰肼(氨基脲,氨基脲和氨基胍)合成芳基hydr的反应,该反应发生在室温和与非对映选择性一起产生了很好的产品收率。程序也简单干净。
