beneficial biological effects of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) a number of polyunsaturated fatty acids containing sulfur or oxygen atoms in the chain has been synthesized starting from EPA and DHA, respectively. Oxidative degradation of these acids led to the corresponding aldehydes all-(Z)-3,6,9,12-pentadecatetraenal and all-(Z)-3,6,9,12,15-octadecapentaenal. Reactions with
为了选择性增强二十碳五烯酸(EPA)和二十二碳六烯酸(DHA)的有益生物学作用,已经分别从EPA和DHA开始合成了链中含有硫或氧原子的许多多不饱和脂肪酸。这些酸的氧化降解导致相应的醛全-(Z)-3,6,9,12-十五碳烯醛和全-(Z)-3,6,9,12,15-十八碳烯醛。与DBU的反应分别将这些醛定量地转化为共轭异构体(2E,6Z,9Z,12Z)-十五碳烯醛和(2E,6Z,9Z,12Z,15Z)-十八碳烯醛。通过一系列反应将四种醛转化,所述反应包括还原成醇,卤化并用巯基酯取代成相应的含硫多不饱和脂肪酸酯。
