(5Z,8Z,10E,14E)-12-Hydroxyeicosa-5,8,10,14-tetraenoic acid [(S) and (R,S)-enantiomers], (R,S)-(5Z,8Z,10E,14Z)-12-hydroxy-5,6,8,9-tetradeuterio-5,8,10,14-tetraenoic acid, (R,S)-(5Z,8E,10E)-12-hydroxyheptadeca-5,8,10-trienoic acid, and (R,S)-(5Z,8E,10E)-12-hydroxy-5,6,8,9-tetradeuterioheptadeca-5,8,10-trienoic acid have been prepared by total synthesis. Deuterium was introduced at selected sites by partial
(5 Z,8 Z,10 E,14 E)-12-羟基5,8,10,14-丁烯酸[(S)和(R,S)-对映体],(R,S)-(5 Z,8 Z,10 E,14 Z)-12-羟基-5,6,8,9-四氘代5,8,10,14-丁烯酸,(R,S)-(5 Z,8 E, 10 E)-12-hydroxyheptadeca-5,8,10-trienoic acid和(R,S)-(5 Z,8 E,10 E通过全合成制备了)-12-羟基-5,6,8,9-四氘七庚烯-5,8,10-三烯酸。通过部分还原将氘引入选定的位置。所有的酸均由常见的中间体10,10-二乙氧基癸基-5,8-二烯酸乙酯制备。(S)-(7h)的cd光谱证实了其与天然产物的同一性。
