Efficient palladium(0)-catalyzed Suzuki-Miyaura cross-couplings are described. The reactions involving potassium aryl- and heteroaryltrifluoroborates with alkenyl bromides can generally be carried out using ≤2 mol % of palladium catalyst and 3 equiv of ba

Isoflavone derivatives were synthesized via intramolecular cyclization of 3-(2-bromophenyl)-3-oxopropanal derivatives, using CuI as the catalyst, 2-picolinic acid (=pyridine-2-carboxylic acid) as the ligand, K 2CO3 as the base, and DMF as the solvent, in up to 96% yield. The synthesis is functional group-tolerant. Copyright
Pd-Catalyzed efficient cross-couplings of 3-iodochromones with triarylbismuths as substoichiometric multicoupling organometallic nucleophiles

An efficient cross-coupling of 3-iodochromones with triarylbismuths under catalytic palladium conditions is reported. Triarylbismuths were employed as substoichiometric multicoupling nucleophiles for the synthesis of a variety of substituted isoflavones.
