A new, straightforward synthesis of highly functional β-carboline building blocks is presented that makes use of allylic amidation methodology. The products obtained carry a terminal double bond as well as an easy-to-deprotect amide, which make them perfectly suitable for further functionalization. The use of the trifluoroacetamide group is exploited in a dual fashion; it acts as a protecting group and functions as the nucleophile for the allylic amidation reaction.
本文介绍了一种利用烯丙基酰胺化方法直接合成高功能δ-咔啉构筑基块的新方法。获得的产物带有一个末端双键和一个易于脱保护的酰胺,这使它们非常适合进一步功能化。三氟乙酰胺基团的使用具有双重作用:既是保护基团,又是烯丙基酰胺化反应的亲核体。
