A new [3 + 4] cycloaddition of azaoxyallyl cations and anthranils has been achieved for rapid access to multisubstituted benzodiazepine derivatives. A variety of anthranils and α-halo hydroxamates were both effective substrates with simple operations under transition-metal-free conditions. The intriguing features of this method include its mild nature of the reaction conditions, high efficiency, broad
为了快速获得多取代的苯并二氮杂衍生物,已经实现了新的[3 + 4]氮杂烯丙基阳离子和蒽基的环加成反应。多种蒽类和α-卤代异羟肟酸酯都是有效的底物,在无过渡金属的条件下操作简单。该方法的引人入胜的特征包括其反应条件温和的性质,高效率,广泛的底物范围和广泛的官能团相容性。
