通过α-重氮-β-二酮与醛酮的环加成反应合成4H-1,3-二噁环己-5-烯-4-酮衍生物

Synthesis of 4H-1,3-Dioxin-4-one Derivatives by Cycloaddition of α-Diazo-β-diketone with Aldehyde and Ketones

研究了 α-重氮 -β-二酮与各类羰基化合物的环加成反应 ,合成了一系列 4H-1 ,3 -二口恶环己 -5 -烯-4 -酮衍生物。

Diazo-β-diketone is a kind of important synthon, which have been widely used in synthesis of various heterocyclic compounds. The cycloaddition reactions of α-diazo-β-diketone with aldehydes and ketones have been studied and a series of 2,2,5,6-tetrasubstituted 4[WT5BX]H-1,3-dioxin-4-ones have been synthesized.
