3-Substituted 1H,5H-naphtho[1,8-ef][1,3]dithiocines (R = H, Me, Ph, t-Bu) were oxidized with m-chloroperoxybenzoic acid to the corresponding 2-oxides having trans configuration (R ≠ H). According to the 1H and 13C NMR data (including NOESY experiments), the disubstituted compounds at room temperature exist in a boat conformation with equatorial orientation of the substituent on C3 and oxygen atom on S2. The compound with no substituent on C3 gives rise to a mixture of boat conformers with axial and equatorial sulfoxide oxygen atoms at a ratio of 83:17.
3-取代的 1H、5H-萘并[1,8-ef][1,3]二硫杂环丁烷(R = H、Me、Ph、t-Bu)被间氯过氧苯甲酸氧化成反式构型(R≠H)的相应 2-氧化物。根据 1H 和 13C NMR 数据(包括 NOESY 实验),二取代化合物在室温下呈舟形构象,C3 上的取代基和 S2 上的氧原子呈赤道取向。而 C3 上没有取代基的化合物则产生了轴向和赤道亚砜氧原子比例为 83:17 的舟形构象混合物。
