Direct synthesis of heteroarylethynes via palladiumcatalyzed coupling of heteroaryl halides with ethynylzinc halides. Its application to an efficient synthesis of a thiophenelactone from chamaemelum nobile

A variety of terminal alkynes containing a heteroaryl group can be directly and selectively synthesized by the Pd-catalyzed coupling of heteroaryl iodides or bromides with ethynylzinc halides. Various compounds of this class containing furan, thiophene, and pyridine have been prepared, and the procedure has been applied to an efficient and selective synthesis of a thiophenelactone from Chamaemelum nobile L.
