13,17-tetraethyl-7,18-dimethyl-25,29-dioxasapphyrin (2) and 3,7,18,22-tetraethyl-2,8,17,23-tetramethyl-27-thiasapphyrin (3). In addition the syntheses of two completely new heteroatom substituted sapphyrins; 3,7,18,22-tetraethyl-2,8,17,23-tetramethyl-27-oxasapphyrin (4) and 7,18-diethyl-8,17-dimethyl-25,29-dioxa-27-thiasapphyrin (5), and described in detail. The procedures described provide facile routes
据报道,合成了3,8,12,13,17,22-六乙基-2,7,18,23-四甲基-七叶红素(1)。还介绍了用于形成8,12,13,17-四乙基-7,18-二甲基-25,29-二氧杂叶黄素(2)和3,7,18,22-四乙基-2,8,17的新合成方法,23-四甲基-27-硫杂卟啉(3)。此外,还合成了两种全新的杂原子取代的血红素。3,7,18,22-四乙基-2,8,17,23-四甲基-27-草as红素(4)和7,18-二乙基-8,17-二甲基-25,29-二氧杂-27-硫杂草皮素(5)),并进行了详细说明。所描述的程序为扩展的卟啉大环化合物之一的代表性成员提供了一条便捷的途径。
