2-pyridinylmethyl sulfoxides and β-imino sulfoxides was sought. The latter were obtained in tautomeric mixtures with their enamines by condensation of optically active β-keto sulfoxides with primary amines. 2-Pyridinylmethyl sulfoxides were synthesized by sulfinate substitution. Titanium catalysed oxidation gave good results for the synthesis of (+)-8-(methylsulfinyl)quinoline from the corresponding
寻求获得对映体纯的2-吡啶基甲基亚砜和β-亚氨基亚砜。后者是通过将旋光性β-酮亚砜与伯胺缩合而与它们的烯胺以互变异构体混合物的形式获得的。通过亚磺酸酯取代合成2-吡啶基甲基亚砜。钛催化的氧化为由相应的硫化物合成(+)-8-(甲基亚磺酰基)喹啉提供了良好的结果。
