    • Provided is a process in which cyclization of a compound having, in a molecule, a formyl group and a double bond which allow carbonyl-ene cyclization, the compound existing as a mixture of optical isomers thereof, increases the ratio of a particular optical isomer not only in a cyclized compound, but also in an unreacted compound. The process comprises performing, in the presence of a specified aluminum complex represented by the general formula: [Al2(L1)n(L2)3-n]m, cyclization of a compound having, in a molecule, a formyl group and a double bond which allow carbonyl-ene cyclization, the compound existing as a mixture of optical isomers thereof, to increase the ratio of a particular optical isomer.
    • 提供一种方法,其中在分子中使具有允许羰基环环化的甲酰基和双键的化合物作为其光学异构体的混合物存在的化合物的环化增加了特定光学异构体的比例 仅在环化化合物中,而且在未反应的化合物中。 该方法包括在由通式[Al2(L1)n(L2)3-n] m表示的规定的铝络合物的存在下进行,分子中具有甲酰基和双 允许羰基环环化的键,作为其光学异构体的混合物存在的化合物,以增加特定光学异构体的比例。
