complex intermediate, followed by intramolecular hydrogen transfer to the iminium carbon. This method is useful for the synthesis of 4-pentynylamine derivatives from enamides and easily available propargyl ether. Moreover, tandem cyclization reaction was achieved to afford a pyrrolidine derivative in a single operation by using a secondary enamide.
通过将酰胺的1,4-加成到α,β-不饱和卡宾配合物中间体上,然后将分子内的氢转移到
亚胺碳上,可以以高收率实现酰胺的加氢炔丙基化。该方法可用于由酰胺和容易获得的
炔丙基醚合成4-
戊炔胺衍
生物。此外,通过使用仲烯酰胺在一次操作中实现串联环化反应以提供
吡咯烷衍
生物。
