We discovered that a reagent comprising a combination of PhBCl2 and nitriles was useful for syntheses of both 3-acylindoles and 1-(1H-indol-3-yl)alkylamine from indoles. The reaction proceeded selectively at the 3-position of indoles providing 3-acylindoles in moderate to high yields on treatment with the above reagent. Furthermore, the reaction provided the corresponding amine products in moderate
The generation of 3-indolylacyl radicals from the corresponding phenylselenoesters and the scope of their participation in intermolecularadditionreactions to carbon-carbon double bonds under both reductive and nonreductive conditions have been studied.
已经研究了在还原和非还原条件下从相应的苯基硒酸酯生成3-吲哚基的自由基及其在分子间加成反应的范围。
Rhodium(I)-Catalyzed Arylation of β-Chloro Ketones and Related Derivatives through Domino Dehydrochlorination/ Conjugate Addition
Highly efficient arylations of β‐chloro ketones and their ester and amide derivatives were achieved by means of domino dehydrochlorination/Rh(I)‐catalyzed conjugate addition. In situ generated vinyl ketones and their analogues were identified as the reaction intermediates. The present synthetic protocol provides a concise route to (chiral) β‐aryl ketones, esters, and amides.
