Suzuki-Miyaura cross coupling of 4-bromo-1-butyl-9-BBN produces 4-hydroxybutyl products evidently arising from a boron-assisted hydroxide substitution. This process was utilized in the synthesis of (±)-2-methoxy-5Z-hexadecenoic acid methyl ester (1), a derivative of the phospholipids isolated from the Caribbean sponge, Spheciospongia cuspidifera.
4-溴-1-丁基-9-BBN的Suzuki-Miyaura交叉偶联可产生4-羟基丁基产物,这显然是由硼辅助的氢氧化物取代引起的。该过程用于合成(±)-2-甲氧基-5Z-十六碳烯酸甲酯(1),其是从加勒比海海绵(Spheciospongia cuspidifera)分离的磷脂的衍生物。
