有效合成5-硝基呋喃烯衍生物(英文)

An Efficient Synthesis of 5 Nitrofuran Olefin Derivatives

报道了一种有效合成５－硝基呋喃烯衍生物的方法。在常温、弱碱Ｋ２ＣＯ３存在下（ｔｒａｃｅＨ２Ｏ），５－硝基呋喃亚甲基溴化金申盐与芳醛反应，高产率、高立体选择性地得到５－硝基呋喃烯衍生物。

Nitrofuran olefins were synthesized by the reaction of triphenyl 5 nitrofural arsonium bromide and aromatic aldehydes in the presence of K 2CO 3(trace H 2O) at room temperature in high stereoselectivities and excellent yields.
