Lithiation and trapping at convenient temperatures (0/−10 °C) of five cyclic sulfides such as tetrahydrothiophene, tetrahydrothiopyrans and a thiomorpholine enables straightforward α-functionalisation. Trapping with a wide range of electrophiles generates more than 50 diverse α-substituted saturated sulfur heterocycles that are not easily synthesised by the currently available methods. TMEDA=N,N,N′
五种环状硫化物(例如四氢噻吩、四氢噻喃和硫代吗啉)在方便的温度(0/−10 °C)下进行锂化和捕获,可实现直接的 α 官能化。用多种亲电子试剂捕获会产生 50 多种不同的 α-取代饱和硫杂环,这些杂环不易通过当前可用的方法合成。 TMEDA= N,N,N′,N′-四甲基乙二胺
