afford 2,3-dihydroisoxazoles (2,3-dihydroisoxazoles can be easily isolated by filtration) in excellent yields under mild and environmentally benign conditions. A one-pot reaction in tandem with an unexpected ring-opening of 2,3-dihydroisoxazoles has been developed as well.
Abstract The current work described a new and highly selective method for the synthesis of substituted 3-cyano-2-pyridones scaffolds using gold-cobalt supported on TiO2 as a robust and recyclable catalyst. The products were successfully obtained by one-pot, multicomponent manner. This procedure generated the desired products 2-pyridones derivatives in good yields, from simple and available starting
摘要 当前的工作描述了一种新的且高度选择性的方法,该方法使用负载在TiO 2上的金-钴作为坚固且可回收的催化剂来合成取代的3-氰基-2-吡啶酮支架。通过一锅多组分方式成功获得了产品。该方法使用多相且可重复使用的催化剂,从简单且可用的起始原料中,以高收率生成了所需的产物2-吡啶酮衍生物。制备了3-氰基-2-吡啶酮衍生物的多样性,并通过IR,1 H和13 C NMR数据进行了表征,并通过元素分析数据进行了证实。 图形摘要
