one-pot synthesis of (all-E)-retinoic acid and related compounds from new enamino diester synthons is described. The enamino diesters was produced nearly quantitatively from methyl propylidene- and isopropylidenemalonate and DMF−DMA. This easy process allowed retinoic acid to be produced in 1 d and appeared advantageous to current industrial syntheses. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim
描述了从新的烯氨基二酯合成子一锅合成 (all-E)-视黄酸和相关化合物。烯氨基二酯几乎定量地从亚丙基丙二酸甲酯和异亚丙基丙二酸酯以及 DMF-DMA 中产生。这种简单的过程允许在 1 d 内生产视黄酸,并且似乎有利于当前的工业合成。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
