The chemo- and diastereoselective reduction of chiral piperidine β-enamino esters 4 and 6 and β-enamino ketones 5 and 7 was studied and found to afford 2,3- or 2,3,6-substituted piperidines. This approach was successfully applied to the total synthesis of (–)-deoxocassine. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
研究了手性哌啶 β-烯氨基酯 4 和 6 以及 β-烯氨基酮 5 和 7 的化学和非对映选择性还原,发现可提供 2,3- 或 2,3,6- 取代的哌啶。该方法已成功应用于 (-)-deoxocassine 的全合成。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
