Starting from (all-Z)-icosa-5,8,11,14,17-pentaenoic acid [(all-Z)-eicosa-5,8,11,14,17-pentaenoic acid, EPA] and (all-Z)-docosa-4,7,10,13,16,19-hexaenoic acid (DHA) several trifluoromethyl ketones, containing sulfur or oxygen atoms at the β-position, have been synthesized as potential inhibitors of cytosolic phospholipase A2. As part of this work EPA and DHA have been oxidatively degraded to (all-Z)-pentadeca-3,6,9,12-tetraenal and (all-Z)-octadeca-3,6,9,12,15-pentaenal, respectively, in 75% overall yields.
从(全-Z)-5,8,11,14,17-二十碳五烯酸[(全-Z)-5,8,11,14,17-二十碳五烯酸,EPA]和(全-Z)-4,7,10,13,16,19-二十二碳六烯酸(DHA)出发,已经合成了几种含有硫或氧原子在β位的三氟甲基酮,这些化合物被认为是细胞质磷脂酶A2的潜在抑制剂。作为这项工作的一部分,EPA和DHA分别被氧化降解为(全-Z)-3,6,9,12-十五碳四烯醛和(全-Z)-3,6,9,12,15-十八碳五烯醛,总产率均为75%。
