palladium catalyzed reaction of butadiene and ethyl acetoacetate was converted to 4,9-decadienoate. Hydroboration of the terminal olefin gave 10-hydroxy-4-decenoate. After hydrogenation and protection of the hydroxyl group, the double bond was created at the conjugated position by introduction of phenylseleno group and subsequent oxidative removal to give 10-hydroxyl-2-decenoic acid.
通过钯催化丁二烯和乙酰乙酸乙酯反应获得的2-乙酰基-4,9-癸二烯酸乙酯转化为4,9-癸二烯酸。末端烯烃的硼氢化得到10-羟基-4-癸烯酸酯。羟基加氢和保护后,通过引入苯基硒基并随后氧化去除,在共轭位置产生双键,得到 10-羟基-2-癸烯酸。
