  A chemoselective Reformatsky–Negishi approach to α-haloaryl esters

  摘要：

  A practical synthesis of alpha-haloaryl esters has been achieved via a chemoselective Negishi coupling of poly-halogenated aromatics and Reformatsky reagents in the presence of catalytic Pd(dba)(2) and Xantphos. This chemistry tolerates a variety of aryl halides and was successfully applied to the synthesis of Ibuprofen. The alpha-haloaryl ester products, exemplified by ethyl 2-(4-bromo-2-chlorophenyl)acetate (3a), can be further functionalized via palladium or copper catalysis to afford an array of a-aryl esters.

  The palladium-catalyzed cross-coupling reaction of tricyclopropylbismuth with aryl and heterocyclic halides and triflates is reported. The reaction tolerates numerous functional groups and does not require anhydrous conditions. The method was successfully extended to the cross-coupling of triethylbismuth.
