一般描述

SPhos Pd G3 是一种 第三代(G3) Buchwald 预催化剂,可用于交叉偶联反应,形成C-C、C-N、C-O、C-F、C-CF3 和 C-S 键。它对空气、水分和热均具有稳定性,并且可溶于多种常见有机溶剂。其独有特征包括催化剂负载量低、反应时间短、有效形成催化物质以及精确控制配体:钯比率。

应用

SPhos Pd G3 可作为 Suzuki-Miyaura 催化剂-转移聚合(SCTP)反应的预催化剂,包括富电子和缺电子(杂)芳烃。它还被用作催化剂,在位阻硼半聚物和醌二叠氮之间形成 Csp3–Csp2 键,这是阿扎咪酮对映选择性合成的关键中间步骤。

A concise and selective synthesis of the dichlorinated meroterpenoid azamerone is described. The paucity of tactics for the synthesis of natural-product-relevant chiral organochlorides motivated the development of unique strategies for accessing these motifs in enantioenriched forms. The route features a
