(1R,2S,2'R)-1-Phenyl-2-(2-naphthylthio)-2-(tetrahydropyran-2'-ylthio)-ethanol 2, (1R,2S,2'S)-1-phenyl-2-(2-naphthylthio)-2-(tetrahydropyran-2'-ylthio)ethanol 3, and 2-[1-butyl-1-(2-naphthylthio)pentylthio]tetrahydropyrane 4 were synthesized from lithiated 2-(2-naphthylthiomethylthio)tetrahydropyran 1. The X-ray single-crystal structures Of 2-4 were determined and the structural features, especially S-sidechain orientation at the 2-position of the THP-ring, bond lengths, and hydrogen bonding were compared to six hydroxyalkylated 2-(phenylthiomethylthio)tetrahydropyrans.
(1R,2S,2'R)-1-苯基-2-(2-萘基硫基)-2-(四氢吡喃-2'-基硫基)-乙醇 2、 (1R,2S,2'S)-1-苯基-2-(2-萘基硫基)-2-(四氢吡喃-2'-基硫基)乙醇 3 和 2-[1-丁基-1-(2-萘基硫基)戊基硫基]四氢吡朗 4 由锂化的 2-(2-萘基硫基甲基硫基)四氢吡喃 1 合成。通过 X 射线单晶衍射确定了 2-4 的结构,并与六种羟基烷基化的 2-(苯基硫基甲基硫基)四氢吡喃在 THP 环的 2 位硫侧链取向、键长和氢键等结构特征进行了比较。
