A selective total synthesis of [11,12-3H]-9-cis-retinoic acid 1 at a specific activity of 46 Ci/mmole is described. The alkyne 4, efficiently prepared in two steps from readily available starting materials, was partially reduced to 9,11-di-cis-retinoic acid 3 with both deuterium and tritium gas. Selective isomerization of 3 to 1 is discussed, as well as non-selective direct conversions of 4 to 1.
描述了一种具有特定活性为46 Ci/mmol的[11,12-3H]-9-顺式-视黄酸1的选择性全合成方法。通过两步高效地从容易获得的起始材料制备得到的炔4,与氘气和氚气部分还原得到9,11-二顺式-视黄酸3。讨论了3到1的选择性异构化,以及4到1的非选择性直接转化。
