Patent ID: 8716500

Claim:
A method for producing a five-membered ring-containing compound represented by the following chemical formula (II): wherein in the formula (II), R 1 may contain a substituent and is selected from a hydrocarbon ring group, a heterocyclic group, a hydrocarbon ring-containing alkyl group, a heterocycle-containing alkyl group, an alkyl group, an alkenyl group, an alkynyl group, an alkyl thioether-containing alkyl group, a heterocyclic group-containing alkyl thioether group, a hydrocarbon ring group-containing alkyl ether group and an alkyloxycarbonyl group; A 1 is an aldehyde group or a hydroxymethyl group obtained by reduction thereof; and among the configuration symbols, represents the α-configuration and represents the β-configuration, the method comprising a cyclization step of condensing and cyclizing an α,β-unsaturated nitro compound represented by the following chemical formula (I): wherein in the formula (I), R 1 is as described above, with a 1,4-butanedione compound, in the presence of a catalyst formed by a compound having a pyrrolidine ring and an optically active α-carbon relative to the nitrogen on the ring, in a water-insoluble organic solvent and/or a non-oxygen atom-containing water-soluble organic solvent.
