  Palladium-Catalyzed α-Arylation of 2-Chloroacetates and 2-Chloroacetamides

  摘要：

  A method has been developed for the Pd-catalyzed synthesis of alpha-(hetero)aryl esters and amides through a Suzuki-Miyaura cross-coupling reaction. This method avoids the use of strong base, does not necessitate inert or low temperature formation of reagents, and does not require the use of a large excess of organometallic reagent. Utilization of organotrifluoroborate salts as nucleophilic partners allows a variety of functional groups and heterocyclic compounds to be tolerated.

  Nickel-Catalyzed C−O Activation of Phenol Derivatives with Potassium Heteroaryltrifluoroborates

  摘要：

  A general method based on nickel-catalyzed C-O activation of various phenol derivatives with potassium (hetero)aryltrifluoroborates has been developed. A large number of heterobiaryls can be easily obtained with yields up to 99% using methanesulfonate cross-coupling partners.

  the Suzuki cross-coupling of unprotected thienylsulfonamides from air- and bench-stable organotrifluoroborates in the absence of a protecting group on the sulfonamide nitrogen. The developed synthetic method can be applied to the preparation of various arylated and heteroarylated thienylsulfonamides under conditions that are tolerant of a broad range of functional groups.

  在磺酰胺氮上没有保护基团的情况下，已经开发了一种温和、实用的方案，用于将未受保护的噻吩磺酰胺与空气和台式稳定的有机三氟硼酸盐进行 Suzuki 交叉偶联。所开发的合成方法可用于在耐受广泛官能团的条件下制备各种芳基化和杂芳基化噻吩磺酰胺。
• Method for Accessing Nitrogen-Containing, <i>B</i>-Heteroaryl-Substituted 2,1-Borazaronaphthalenes

  The azaborine motif provides a mimic of aromatic systems through replacement of a C═C bond with a B-N bond. In particular, 2,1-borazaronaphthalenes, accessible through robust methods of synthesis and subsequent functionalization, afford an ideal platform to use for a variety of applications. However, the scope of substructures for this archetype has been limited by the lack of nitrogen-containing heteroaryls that can be incorporated within them. In this study, modified reaction conditions were developed to provide access to a wider range of substructures.
