Description

technical field

[0001] The present invention relates to a method for producing farnesal from (E)-nerolidol using a vanadium complex. In addition, the present invention relates to a novel vanadium complex and a method for producing the same. Background technique

[0002] Farnesal (3,7,11-trimethyl-2,6,10-dodecatrienal) is known to be an important compound used as an intermediate in the production of pharmaceuticals, agricultural chemicals, fragrances, and the like. In particular, (2E,6E)-farnesal can be used as an intermediate for the production of polyisoprene derivatives useful as anticancer agents and the like (see, for example, Patent Document 1). There are four isomers of (2E,6E)-body, (2Z,6E)-body, (2E,6Z)-body and (2Z,6Z)-body in farnesal, so for the selective production of ( 2E,6E)-farnesal methods have been studied in various ways.

[0003] For example, the following method is disclosed: using (2E,6E)-farnesol ((2E,6E)-3,7,11-trimethyl-2,6,10-dodecatrien-1-ol) as ...
