prepared using alkenylboronic acids in good to excellent yields (79–97%), and one additional example was prepared from an alkenylstannane in 74% yield. The products display Michael acceptor-like reactivity. The alkenyl fragment quenches the fluorescence of the BODIPY core, which is turned back on by reducing the double bond.
通过Liebeskind-Srogl交叉偶联,从8-
硫甲基取代的BODIPY开始,制备了一系列新的8-链烯基BODIPY
染料。使用链烯基
硼酸制备了十种衍
生物,收率良好至优异(79-97%),另外一个实例是从链烯基
锡烷以74%的产率制备。该产品表现出迈克尔受体样的反应性。烯基片段淬灭了BODIPY核心的荧光,通过还原双键将其重新打开。
