In this study, 8‐iodocoumarin derivatives underwent a direct Stille cross‐coupling reaction with several organotin compounds in the presence of a catalytic amount of Pd(PPh3)4 in DMF at 80 °C. The cross‐coupling reaction proceeded smoothly under mild conditions and permitted the formation of 8‐allyl or 8‐prenylcoumarin compounds in good yields. Copyright © 2012 John Wiley & Sons, Ltd.
在这项研究中,在80°C的DMF中催化量的Pd(PPh 3)4存在下,8-碘docoumarin衍生物与几种有机锡化合物直接进行了Stille交叉偶联反应。交叉偶联反应在温和条件下进行得很顺利,并以高收率形成了8个烯丙基或8个异戊烯基香豆素化合物。版权所有©2012 John Wiley&Sons,Ltd.
