The planar chiral 15-hydroxy[2.2]paracyclophane-4-carbaldehyde (2, iso-FHPC) was synthesized and resolved via its Schiff bases 8 by using the enantiomers of α-phenylethylamine. The absolute configurations of the enantiomers of 2 were determined by a combined X-ray diffraction and chemical correlation study. Derivatives 9, the first representatives of cyclophane-derived aminophenols with a pseudo-gem
合成了平面手性 15-羟基 [2.2] 对环芳烷-4-甲醛 (2, iso-FHPC),并使用 α-苯乙胺的对映异构体通过其席夫碱 8 进行拆分。2 的对映异构体的绝对构型通过组合的 X 射线衍射和化学相关性研究确定。衍生物9,合成了具有假宝石排列的官能团的环芳衍生的氨基苯酚的第一个代表。所有新的手性化合物都可以被视为不对称合成和催化的潜在配体。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
