-
Paragraph 0049; 0050, (2015/03/16)
The present invention relates to a method for preparing a furofuran lignan compound, comprising a step of selecting and alkylating an epoxy alcohol compound and an optical isomer thereof. (+)-furofuran lignan and (?)-furofuran lignan, as well as an optical isomer thereof, can be selectively prepared by means of the method.
