An efficient procedure for the synthesis of 2,2-disubstituted benzocyclic ketones by intramolecular carbopalladation of nitriles has been developed. The cyclization of substituted 3-(2-iodoaryl)propanenitriles affords indanones in high yields. The reaction is compatible with a wide variety of functional groups. This methodology has been extended to the synthesis of tetralones and cyclopentenones.
已经开发出一种通过腈的分子内碳弹头化合成2,2-二取代的苯并环酮的有效方法。取代的3-(2-碘芳基)丙烷腈的环化以高收率提供茚满酮。该反应与多种官能团相容。该方法已经扩展到四氢萘酮和环戊烯酮的合成。
