Fluorination followed by the Michael addition or Robinson annulation of 1,3-dicarbonyl compounds is introduced for the synthesis of acyclic and cyclic α-fluoro-β-ketoesters and α-fluoro-1,3-diketones. The decarboxylation step can also be added to the reaction sequence. High efficiency is achieved by the microwave heating and atom economic one-pot synthesis.
氟化作用然后引入1,3-二羰基化合物的Michael加成反应或Robinson环合反应,以合成无环和环状α-氟-β-酮酸酯和α-氟-1,3-二酮。脱羧步骤也可以添加到反应序列中。通过微波加热和原子经济的一锅合成可以实现高效率。
