method for the construction of a pyridine moiety with selective control of substitution patterns has been developed through the sequential reactions of nitrile with a Reformatsky reagent and 1,3-enyne involving regio- and chemoselective addition of the Blaise reaction intermediate to 1,3-enyne, followed by isomerization, cyclization, and an aromatization cascade.
通过腈与Reformatsky试剂和1,3-烯炔的顺序反应(涉及将Blaise反应中间体与Blaise的区域和
化学选择性加成),开发了一种具有选择性控制取代模式的
吡啶结构的串联一锅法。 1,3-烯炔,然后进行异构化,环化和芳构化级联。
