致力于斯科特丹麦:至此,我们(以及缺席的KB )正在庆祝您的创造力和成就。 发布时间作为的一部分奉献给斯科特E.丹麦在他65之际特别节日的生日。 抽象的 报告了对广泛使用的标题反应过渡金属催化的交叉偶联反应的系统研究,并着眼于定向原金属化(D o M)。通常,Suzuki-Miyaura和Negishi方案比Corriu-Kumada方案具有更大的范围和更高的产量,尽管后者定性地以最快的速度进行,但功能基团的耐受性较低。据证明,Negishi工艺可用于具有亲核试剂和碱敏感功能的底物,其效率可与Suzuki-Miyaura反应媲美。这些交叉偶联反应与D o M策略的联系使其适用于不同取代的芳族化合物和杂芳族化合物的区域选择性结构。 报告了对广泛使用的标题反应过渡金属催化的交叉偶联反应的系统研究,并着眼于定向原金属化(D o M)。通常,Suzuki-Miyaura和Negishi方案比Cor
Development of Photoredox Cross-Electrophile Coupling of Strained Heterocycles with Aryl Bromides Using High-Throughput Experimentation for Library Construction
cross-coupling reaction of aryl halides with strained aliphatic heterocycles facilitated via a ring-openingreaction. This methodology was found to be applicable to medicinally relevant substrates including Boc-protected strained aliphatic heterocycles and (hetero)aryl bromides and was used for compound library construction via parallel medicinal chemistry. Furthermore, the coupling reactions were shown
Nickel(0)-catalyzed cross coupling of aryl O-carbamates and aryl triflates with Grignard reagents. Directed ortho metalation-aligned synthetic methods for polysubstituted aromatics via a 1,2-dipole equivalent
The first Ni(0)-catalyzed cross-coupling reactions of aryl O-carbamates and aryl triflates with Grignard reagents (Scheme I) to give diversely polysubstituted aromatics 2d and 2e (Table I) which feature regiospecificity based on directed ortho metalation (carbamate), minimal beta-hydride elimination (triflate), and dependence on steric and electronic effects are described.
