Bis(tetrahydrofuran) compound, method for production of the compund, and use of the compound

Abstract

The present invention provides a new bis(tetrahydrofuran) compound having an excellent neurotrophic factor activity-enhancing effect, and a process for producing the same. The bis(tetrahydrofuran) compound of the present invention is represented by formula (1): wherein R1 and R2 are the same or different, and represent a C1-4 alkyl group, a C1-5 alkoxy group, an aryl C1-5 alkoxy group, a C2-5 alkenyloxy group, or an aryl C2-5 alkenyloxy group, or R1 and R2 together represent ═O or ═CH2; R3 represents a hydrogen atom or a group —CH2—O—R4; R4 represents a C1-4 alkyl group, a C1-5 alkylcarbonyl group, or an aryl C1-4 alkyl group that may have a substituent on an aryl ring; and a carbon-carbon bond between “a” and “b” represents a single bond or a double bond. The bis(tetrahydrofuran) compound has an excellent neurotrophic factor activity-enhancing effect.
