exploiting the reactivity of arynes. Reaction of N-carbamoyl-functionalized enamine derivatives with benzyne affords substituted indolines. An orthogonal reactivity is uncovered when related enamine derivatives are modified as amides, such that isoquinolines are formed as the product of condensation with benzyne. This latter transformation is applied to a concise total synthesis of the opiate alkaloid papaverine
本报告中描述了两种利用芳炔反应性的独特方法的发展。N-氨基甲酰基官能化的烯胺衍生物与苄的反应提供取代的二氢吲哚。当相关的烯胺衍生物被修饰为酰胺时,就会发现正交反应性,这样异喹啉就可以作为与苄缩合的产物形成。后一种转化适用于鸦片生物碱罂粟碱的简明全合成。
