Pure organic: The synthesis of tetrasubstitutedfurans often involves transition‐metal catalysis or metal–halogen exchange reactions. A new approach to these heterocycles employs the Feist–Bénaryaddition–elimination process using nitroallylicacetates and 1,3‐dicarbonyls (see scheme; X=C, O).
纯有机物:四取代呋喃的合成通常涉及过渡金属催化或金属-卤素交换反应。对这些杂环的一种新方法是采用Feist-Bénary加成-消除工艺,该工艺使用乙酸烯丙酯和1,3-二羰基化合物(请参见方案; X = C,O)。
