摘要:

从真菌草酸青霉菌(Penicillium oxalicum)中分离得到一个新的立体异构体Hydroxyscytalone, 其平面结构采用核磁共振和高分辨质谱等进行确定, 其立体化学通过振动圆二色光谱、 电子圆二色光谱和旋光光谱进行证实.

Abstract:

A new stereoisomer of hydroxyscytalone from Penicillium oxalicum was obtained. Its planar structure was established using 1H NMR, 13C NMR and high resolution MS. In its stereochemistry study, the very recently developed method, vibrational circular dichroism(VCD) was used. The calculation is relatively simple by computing the corresponding characteristics based on ground state of electronics. By comparison of computed VCD, ECD and OR with the experimental data, stereochemistry can be well studied.

Key words: Hydroxyscytalone, Penicillium oxalicum, Vibrational circular dichroism(VCD), Electronic circular dichroism(ECD), Optical rotation(OR)
