The reaction between a variety of o‐phenylenediamines (=benzene‐1,2‐diamines), dialkyl acetylenedicarboxylates, and derivatives of nitrostyrene (=(E)‐(2‐nitroethenyl)benzene) in the presence of sulfamic acid (SA; H3NSO3) as catalyst led to the corresponding pyrrolo[1,2‐a]quinoxaline‐4(5H)‐one derivatives in high yields.
在氨基磺酸(SA; H)存在下,各种邻苯二胺(=苯-1,2-二胺),乙二酸二烷基酯与硝基苯乙烯衍生物(=(E)-(2-硝基乙烯基)苯)之间的反应3 NSO 3)作为催化剂可高产率生成相应的吡咯并[1,2- a ]喹喔啉-4(5 H)-one衍生物。
