Title:
METHOD FOR PRODUCING OPTICALLY ACTIVE 2,3-DIHYDROFARNESAL
Document Type and Number:
WIPO Patent Application WO/2014/038665
Kind Code:
A1
Abstract:
A method for producing optically active 2,3-dihydrofarnesal represented by formula (1), characterized by aminating β-farnesene represented by formula (2) in the presence of a lithium salt of an amine to produce a (2E)-farnesylallylamine represented by general formula (3), then asymmetrically isomerizing the (2E)-farnesylallylamine to produce an optically active farnesyl enamine represented by general formula (3), and then solvolyzing the optically active farnesyl enamine (in the formulae, R1, R2 and * are as defined in the claims of the present application).
