  Microwave-Mediated Suzuki–Miyaura Cross-Couplings of Thioether- and ortho-Substituted Methylphenylboronic Acid Esters

  摘要：

  Hiterto unsuccessful cross-couplings of ortho-substituted or thioether-substituted methylphenylboronates have now been achieved, under microwave conditions, enabling the synthesis of a library of novel biaryls. Tetrakis(triphenylphosphine) palladium and various bases, for example, sodium carbonate or cesium fluoride, were found to mediate the crucial C-C bond-forming cross-coupling reaction.

  A series of arylboronates has been synthesized from the reaction of 2-(2-, (3-, or (4-(bromomethyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 11-3) respectively with a range of N-, S-, and O-nucleophiles, using microwave-mediated chemistry. For the synthesis of N- and S-substituted boronates, a supported base, PS-NMM, was employed, and many reactions were complete within 15 min. With O-nucleophiles, a mixture of tetrabutylammonium bromide, potassium carbonate, and sodium hydroxide was employed. The resulting aminomethyl, mercaptomethyl, or alkoxy-/phenoxymethyl-arylboronates were subjected to microwave-mediated Suzuki Miyaura coupling reactions to afford a range of biaryls in moderate to good yields. The X-ray structures of five boronates were determined.
