one pot approach for the synthesis of various nitrogen containing heterocycles including: oxazolines, thiazolines, and dihydro dioxazines via the addition of amides to olefins in the presence of N-iodosuccinimide (NIS) and propionitrile at high temperatures. Thus, the reaction of aryl/heteroaryl amides, thioamides, N-hydroxybenzamide, and phenylurea with various olefins in the presence of NIS and propionitrile
我们在本文中报道了在高温下在N-碘代琥珀酰亚胺(NIS)和丙腈的存在下通过将酰胺加成到烯烃中来合成各种含氮杂环的一锅法,这些杂环包括:恶唑啉,噻唑啉和二氢二恶嗪。因此,在NIS和丙腈的存在下,芳基/杂芳基酰胺,硫代酰胺,N-羟基苯甲酰胺和苯基脲与各种烯烃的反应在45°C下以良好至中等的产率提供了N-杂环。的缺电子反应三ø乙酰基d -glucal和三ö乙酰基dβ-半乳糖与苯甲酰胺和噻吩-2-羧酰胺的收率很好。测试了新制备的杂环抗各种酶的能力。仅3,6-二苯基-二氢-1,4,2-二恶嗪(1c)被发现可适度抑制己糖激酶II(hHK2)。
