ABSTRACT The reaction of the 2′-hydroxychalcone dibromides with azide ion was found to afford various products such as α-azido-2′-hydroxychalcones, flavones, aurones, isoxazoles or the parent chalcones depending on the substituent pattern of the substrate. Efficient transformation of α-azido-2′-hydroxychalcones to 3-amino-2-substituted chromones was also demonstrated.
摘要 2'-羟基查尔酮二溴化物与叠氮离子的反应被发现提供各种产物,如 α-叠氮基-2'-羟基查尔酮、黄酮、aurone、异恶唑或母体查耳酮,这取决于底物的取代模式。还证明了 α-叠氮基-2'-羟基查耳酮向 3-氨基-2-取代的色酮的有效转化。
