2-Hydroxy-2′-methoxydiphenyl ethers were efficiently assembled utilizing a catalytic copper mediated coupling of 2-benzyloxybromobenzene derivatives and 2-methoxyphenol derivatives in the presence of cesium carbonate in pyridine followed by debenzylation. Utilization of this method allowed for a concise synthesis of verbenachalcone, a compound reported to enhance nerve growth factor's ability to stimulate
在吡啶中碳酸铯存在下,利用催化铜介导的2-苄氧基溴苯衍生物和2-甲氧基苯酚衍生物的偶合反应,有效地组装了2-羟基-2'-甲氧基二苯基醚。利用该方法可以简明合成马鞭草酚酮,该化合物据报道可增强神经生长因子刺激PC12D细胞中神经突生长的能力。还显示了初始SAR数据。
