A process of preparing an unsaturated alcohol (olefin alcohol), such as, a homo-allylic mono-alcohol or homo-allylic polyol, involving protecting a hydroxy-substituted unsaturated fatty acid or fatty acid ester, such as methyl ricinoleate, derived from a seed oil, to form a hydroxy-protected unsaturated fatty acid or fatty acid ester; homo-metathesizing or cross-metathesizing the hydroxy-protected unsaturated fatty acid or fatty acid ester to produce a product mixture containing a hydroxy-protected unsaturated metathesis product; and deprotecting the hydroxy-protected unsaturated metathesis product under conditions sufficient to prepare the unsaturated alcohol. Preferably, methyl ricinoleate is converted by cross-metathesis or homo-metathesis into the homo-allylic mono-alcohol 1-decene-4-ol or the homo-allylic polyol 9-octadecene-7,12-diol, respectively.
一种制备不饱和醇(烯醇)的过程,例如,保护羟基取代的不饱和脂肪酸或脂肪酸酯,例如来自种子油的甲基蓖麻油酸甲酯,形成羟基保护的不饱和脂肪酸或脂肪酸酯; 同型交换或交叉交换羟基保护的不饱和脂肪酸或脂肪酸酯,以产生含有羟基保护的不饱和交换产物的产物混合物; 并在足以制备不饱和醇的条件下去除羟基保护的不饱和交换产物。优选地,通过交叉或同型交换将甲基蓖麻油酸甲酯转化为同型烯丙基单醇1-癸烯-4-醇或同型烯丙基多醇9-十八烯-7,12-二醇。
