Title:
METHOD FOR PRODUCING SANSHOOL
Document Type and Number:
WIPO Patent Application WO/2012/073910
Kind Code:
A1
Abstract:
Provided are a method for producing a sanshool, the method having a short process and being highly stereoselective, and an iron carbonyl complex compound which is a useful intermediate for the method of production. A diene iron complex compound is characterized by being represented by General Formula (I) (in the formula, A represents CO, P(RA)3, CN, NO, SO(RA)2, or N(RA)2, where RA represents a C1-4 linear or branched alkyl group, or a C6-12 aryl group; either one of R1 and R2 represents a hydrogen atom, and the other has the structure represented by General Formula (II)) (in the formula, R represents a hydrogen atom, a hydroxyl group, or a methyl group).
