good yields. Aryldiazonium salts that have an electron-donating substituent underwent a smooth reaction in the presence of Pd2dba3. A palladium complex that coordinated with an electron-rich ligand was necessary for the reaction to progress with electron-deficient aryldiazonium salts. An optically active allylic nitro compound underwent reaction without the loss of optical purity at the stereogenic
烯丙基硝基化合物的 Heck-Matsuda 反应有效地以良好的产率提供了肉桂基硝基化合物。具有给电子取代基的芳基重氮盐在 Pd2dba3 存在下进行了平稳的反应。与富电子配体配位的钯配合物是与缺电子芳基重氮盐进行反应所必需的。光学活性烯丙基硝基化合物在立体中心没有光学纯度损失的情况下进行反应。通过这种方法实现了光学活性 FTY720 衍生物的快速合成。
