摘要：

Suzuki cross-coupling reaction with sterically hindered arylboronic acids is reported. Good yields are obtained by using DME and cesium fluoride in the presence of Pd(OAc)(2) and triphenylphosphine. The catalytic asymmetric reaction between 2-methoxy-1-naphthylboronic acid and 1-iodo-2-methoxynaphthalene was studied in the presence of a palladium-chiral phosphine catalyst. When the reaction was carried out with Pd(OAc), and (R)-BINAP (versus (R)-TolBINAP), the enantioselection was dramatically influenced by the phosphine palladium ratio.
