简单不饱和单糖的x射线晶体学结构数据不支持C2-C3 π键的电子密度参与了异头中心几何形状的改变，也不支持糖基中存在葡萄状异头效应。离域现象（n-σ*， n-π*和π-σ*）在单糖的基态中不显著，n-n斥力是这些分子中主要的立体电子效应
The X-ray crystallopraphic structural data for simple unsaturated monosaccharides do not support the participation of the electron density of a C2-C3 π bond in the modification of the geometry at the anomeric center, or the existence of a vinylogous anomeric effect in glycals. The delocalization phenomena (n-σ*, n-π* and π-σ*) are insignificant in the ground states of the simple sugars, and n-n repulsions are the dominant stereo-electronic effects in these molecules
