The palladium-catalysed intramolecular alpha-arylation of carbonyl compounds with amino-tethered 2- and 3-iodoindoles provides a useful methodology for the synthesis of indolo-b-fused nitrogen heterocycles. A variety of substituted tetrahydro beta- and gamma-carbolines, and pyrrolo[3,4-b]indoles, have been prepared by means of this palladium-catalysed annulation process.
钯催化的羰基化合物的分子内α-芳基化与氨基连接的2-和3-碘吲哚提供了一种有用的方法,用于合成吲哚-b-稠合的氮杂环。通过这种钯催化的环化方法已经制备了各种取代的四氢β-和γ-咔啉以及吡咯并[3,4-b]吲哚。
