A modular synthetic scheme has been developed for the synthesis of 13C-labeled naturally occurring visual pigment chromophores; 3,4-didehydroretinal, 3-hydroxyretinal, and 4-hydroxyretinal. These compounds can now be made with > 99% 13C enrichment at any position or combination of positions. We used the common C10+C5+C5 scheme for the synthesis of retinals, and by making variations in the C10 part
已经开发了一种模块化合成方案,用于合成 13C 标记的天然存在的视觉色素发色团;3,4-二脱氢视黄醛、3-羟基视黄醛和4-羟基视黄醛。这些化合物现在可以在任何位置或位置组合上以 > 99% 的 13C 富集率制成。我们使用常见的 C10+C5+C5 方案合成视黄醛,通过改变 C10 部分,我们现在可以制备具有选择性或均匀 13C 富集的所需视黄醛衍生物。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
