Additions of various carbanion nucleophiles to 3,3,3-trifluoro-1-nitropropene (1) proceeded regiospecifically at the C-2 position of 1 to give the corresponding adducts. The nitro group of the adducts, derived from the reactions with acetylacetone and ethyl acetoacetate, was reduced to the corresponding amines, which were cyclized in situ to the 3-(trifluoromethyl)pyrrole derivatives.
将各种碳负离子亲核试剂添加到 3,3,3-三氟-1-硝基丙烯 (1) 中,在 1 的 C-2 位置区域特异性地进行,得到相应的加合物。来自与乙酰丙酮和乙酰乙酸乙酯反应的加合物的硝基被还原为相应的胺,然后原位环化为 3-(三氟甲基)吡咯衍生物。
