xylic acid derivatives, isomers of 2-amino-3-hydroxycyclopentanecarboxylic acid (8 and 12) were prepared via oxazoline intermediates, whereas the stereoisomeric 2-amino-3,4-dihydroxycyclopentanecarboxylic acids 14 and 17 were synthesized by OsO4-catalyzed oxidation. The enantiomers of 8 and 14 were also prepared by the same pathway. The structures, stereochemistry and relative configurations of the
从 N-保护的顺式和反式 2-氨基环戊-3-烯羧酸衍生物开始,通过恶唑啉中间体制备 2-氨基-3-羟基环戊烷甲酸的异构体(8 和 12),而立体异构体 2-氨基-3, 4-二羟基环戊烷羧酸 14 和 17 是通过 OsO4 催化氧化合成的。8 和 14 的对映异构体也通过相同的途径制备。合成化合物的结构、立体化学和相对构型均通过核磁共振波谱证实。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
