Abstract
The invention discloses an intermediate 1-methoxyl-2,6,10-trimethyl-1,3,5, 9-undec-tetraene, and a preparation method and uses thereof. In the synthesis method for the current lycopene intermediate 2-pos double bond C-14 aldehyde (2,6,10-trimethyl-2,5,9-undecatriene-1-aldehyde), expensive methyl iodide, polluting dimethyl sulphide and dangerous strong base are needed, so that the method is hardly applied to industrial production. The invention provides a new compound 1-methoxyl-2,6,10-trimethyl-1,3,5,9-undec-tetraene, and pure 2-pos double bond C-14 aldehyde can be prepared by hydrolyzing and refining the compound. The synthetic route is simplified and the great suitability for industrial production is achieved.
