Enantiopure (R)-(+)-[VCD(+)945]-4-ethyl-4-methyloctane, the simplest chiral saturated hydrocarbon with a quaternary stereogenic center, was synthesized by the use of MαNP acid method, and its absoluteconfiguration was first unambiguously determined by the 1H NMR anisotropy, X-ray crystallography, and VCD methods.
对映体(R)-(+)-[VCD(+)945] -4-乙基-4-甲基辛烷,是一种最简单的手性饱和烃,具有四级立体异构中心,是通过MαNP酸法合成的,其绝对构型首先通过1 H NMR各向异性,X射线晶体学和VCD方法确定。
