α-ketoimidoyl chlorides to AgBF4, readily engage suitably disposed sites of molecular unsaturation in cyclization reactions leading to heterocyclic ring systems. This novel method for annulation is applicable to the construction of 5, 6, and 7 membered rings and is particularly useful for the @Synthesis of polyfunctional heterocycles possessing quaternary sites in the β-position to nitrogen.
通过将α-酮亚氨基酰氯暴露于AgBF 4产生的腈腈离子很容易与环化反应中导致杂环系统的分子不饱和位点适当地结合。这种新颖的环化方法适用于5、6和7元环的构建,并且特别适用于β合成氮的β位具有季位的多官能杂环。
