The conformational analysis of several 2-substituted 1,3-dithianes made possible the evaluation of S-C-Y anomeric interactions, where Y = SCH3, SC6H5, CO2CH3, CO6H5, CO2H and N(CH3)2. The relative magnitude of the effects observed for these groups [ΔG°dithiane(Y) - ΔGδ cyclohexane(Y)] can be explained in terms of the combined influence of dipole/dipole and two-electron stabilizing interactions (stereoelectronic
几个2-取代的1,3-二硫杂环丁烷的构象分析使SCY异头相互作用的评估成为可能,其中Y = SCH 3,SC 6 H 5,CO 2 CH 3,CO 6 H 5,CO 2 H和N(CH 3)2。可以用偶极/偶极和两电子稳定相互作用(立体电子效应)的综合影响来解释对这些基团[ΔG°二噻吩(Y)-ΔGδ环己烷(Y)]观察到的相对影响强度。
