A new series of tetrahydropyridines was isolated when 1-adamantyl or t-butyl mercaptan was added last to a solution of pyridine N-oxide and triethylamine in acetic anhydride. Under these conditions, the predominant tetrahydropyridines proved to be 1-acetyl-2-alkylthio-3-acetoxy-6-hydroxy-1,2,3,6-tetrahydropyridines. These carbinolamides were isomerized in part during silica gel column chromatography
当将1-金刚烷基或叔丁基硫醇最后加入到吡啶N-氧化物和三乙胺的乙酸酐溶液中时,分离出一系列新的四氢吡啶。在这些条件下,主要的四氢吡啶被证明是1-乙酰基-2-烷硫基-3-乙酰氧基-6-羟基-1,2,3,6-四氢吡啶。这些甲醇酰胺在硅胶柱色谱法中部分异构化为反式-4-乙酰氧基-5-烷硫基-5-乙酰氨基-2-戊烯醛。
