An easy approach to mono- and bicyclic derivatives of 5,6-dihydro-1H-pyridine-2-thione via a one-pot ring closing metathesis (RCM) of dialkenoic amides and thionation using Lawesson’s reagent, followed by isomerization of the 3,6-dihydro-isomer (if necessary), is described. The appreciable differences in the reactivity of diallylic amides in RCM reactions are discussed.
一种简单的方法,可以通过二烯键式酰胺的一锅闭环易位(RCM)并使用Lawesson试剂进行硫磺化,从而制得5,6-二氢-1 H-吡啶-2-硫酮的单环和双环衍生物,然后将3异构化描述了,6-二氢-异构体(如果需要的话)。讨论了RCM反应中二烯丙基酰胺反应性的明显差异。
