The invention relates to a novel important lycopene intermediate 3,7, 11-trimethyl-1,3,6,10-tetraene-dodecyl diethyl phosphonate. A current lycopene intermediate 2,4,6,10-tetra-double bond pentadec-carbon phosphonate is difficult to synthesize. The invention provides a novel intermediate, which has the following synthesis steps of: preparing 2,6,10-trimethyl-3,5,9-undecane triene-1-aldehyde from pseudoionone; preparing 2,6,10-trimethyl-2,5,9-undecane triene-1-aldehyde from the 2,6,10-trimethyl-3, 5,9-undecane triene-1-aldehyde; and subjecting the 2,6,10-trimethyl-2,5,9-undecane triene-1-aldehyde and tetraethyl methylenediphosphonate to condensation reaction to obtain target product. The invention can generate novel intermediate from raw material pseudoionone only by four reactions, thus the reactions are easy to control and great industrial value are achieved.
该发明涉及一种新的重要类胡萝卜素中间体3,7,11-三甲基-1,3,6,10-四烯-十二烷基二乙基膦酸酯。目前的类胡萝卜素中间体2,4,6,10-四双键十五碳膦酸酯难以合成。该发明提供了一种新的中间体,其具有以下合成步骤:从伪异香叶酮制备2,6,10-三甲基-3,5,9-十一烯-1-醛;从2,6,10-三甲基-3,5,9-十一烯-1-醛制备2,6,10-三甲基-2,5,9-十一烯-1-醛;并将2,6,10-三甲基-2,5,9-十一烯-1-醛和四乙基甲亚膦酸酯进行缩合反应以获得目标产物。该发明可以仅通过四个反应从原材料伪异香叶酮生成新的中间体,因此反应易于控制且具有重要的工业价值。
