1,3-Dicarbonyl compounds useful as medicines, agricultural chemicals, perfumes, and their intermediates are prepared by reacting a specific .alpha.,.beta.-unsaturated carbonyl compound with a specific organic copper lithium compound in the presence of an aprotic inert organic solvent, and then reacting the reaction product with an organic carboxylic acid halide or anhydride. In particular, novel 2-acyl-3-substituted cyclopentan-1-ones and 2-acyl-3-substituted cyclohexan-1-ones having important physiological activities are provided.
1,3-二羰基化合物,可用作药物、农药、
香料以及它们的中间体,是通过将特定的α,β-不饱和羰基化合物与特定的
有机铜锂化合物在无质子惰性有机溶剂的存在下反应,然后将反应产物与有机
羧酸卤化物或酐反应而制备的。特别是,提供了具有重要生理活性的新型2-酰基-3-取代
环戊烷-1-酮和2-酰基-3-取代
环己烷-1-酮。
