在不同浓度的三乙胺乙酸乙酯溶液中2-甲基环戊-1,3-二酮与氯代甲基乙烯酮(1b)反应可分别得三酮、α-氯代醇或环氧双酮. α-氯代醇经X射线单晶衍射分析结果推断出环氧双酮的环氧是β构型, 其异构体为α, 用相似的方法制得的同系环氧物也经X射线单晶衍射分析, 结果表明其环氧为β构型.

2-Methylcyclopentane-1,3-dione reacts with chloromethyl vinyl ketone to give 2-methyl-2-(4-chloro-3-carbonylbutyl)cyclopentane-1,3-dione, chlorohydrin I or epoxide II as the main product depending on the concentration of Et3N used. X-ray anal. of I shows that the configuration of epoxide in II is b. The homologous epoxide III, prepared in a similar way is shown to be a b-epoxide.
