Cyclic six-membered imines, i.e. 2,3,4,5-tetrahydropyridines, are efficiently converted under mild conditions into the corresponding pyridines by highly regioselective α, α-dichlorination with N-chlorosuccinimide (NCS) followed by double dehydrochlorination with methanolic bases.
循环六元亚胺,即2,3,4,5-四氢吡啶,在温和条件下通过与氯代琥珀酰亚胺(NCS)进行高度区域选择性的α,α-二氯化转化为相应的吡啶,随后与甲醇碱进行双重脱氯化反应,效率很高。
