The syntheses of D- and L-fagomines 1, 4, 5 and 6 and their isomers from starting D-glycals have been achieved. The syntheses involve elaboration of common amino alcohol precursors obtained from 2-deoxy-1-amino sugar derivatives. The key steps in the syntheses are intramolecular reductive amination and intramolecular N-heterocyclization. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany
D-和L-fagomines 1, 4, 5 和 6 及其异构体的合成已由起始 D-乙二醇合成。合成涉及从 2-脱氧-1-氨基糖衍生物获得的常见氨基醇前体的加工。合成的关键步骤是分子内还原胺化和分子内 N-杂环化。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
