The reaction temperature is usually from -30°C to below the boiling point of the aromatic hydrocarbon. Although the reaction time may vary depending on the reaction conditions, the desired reaction time can usually be achieved in 5 minutes to 10 hours. The reaction proceeds advantageously under mild conditions. High purity can be obtained by ordinary isolation procedures, but if necessary, it can be further purified by means such as recrystallization or chromatography.

である。 If optically active pyrosine is used in this reaction, the lactone derivative represented by the formula () produced can also be obtained as an optically active substance. Generally, biologically active compounds exhibit differences in activity depending on their chirality. Therefore, it is of great significance to develop a technology for producing optically active compounds. Therefore, for example, the above-mentioned tonalide derived from the compound of the present invention can be obtained as an optically active form, if desired.
From this point of view as well, the present invention has special features.
