hydrogenation with chiral 1-(9-phenanthryl)ethylamine (1), the (+) isomer (as measured in CHCl3) was assigned the (R) configuration by use of the Zn−porphyrin host-guest CD exciton chirality method after derivatization with 4-[(Boc-amino)methyl]pyridine-2-carboxylic acid, and also directly on the amine by use of the VCD method. Attempts to use the bis(chromophoric) CD exciton chirality method after derivatization
与丙酮酸氢化与手性 1-(9-菲基) 乙胺 (1) 的立体化学结果的预测一致,(+) 异构体(在 CHCl3 中测量)通过使用 Zn-卟啉指定为(R)构型用4-[(Boc-氨基)甲基]吡啶-2-羧酸衍生后的主客体CD激子手性方法,也可以直接使用VCD方法在胺上进行。由于菲基的复杂电子结构,在用萘基衍生化后尝试使用双(发色)CD 激子手性方法碰巧更困难,尽管在这种情况下萘基部分是最合适的发色团。结果进行了讨论。(© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
