Seco-alkaloids 4-7 were treated with VOF3 and VOCl3, under a variety of conditions. No coupled products were detected. However, ring chlorinated and side-chain oxidized products were obtained from the VOCl3 oxidation of 4 and 7 respectively. The generality of the ring chlorination reaction was confirmed by chlorination of simple 0-methoxy phenols under these conditions to yield 17 and 23. In certain
在多种条件下,用VOF 3和VOCl 3处理了Seco-生物碱4-7。未检测到偶联产物。然而,分别从4和7的VOCl 3氧化获得环氯化和侧链氧化的产物。通过在这些条件下对简单的0-甲氧基苯酚进行氯化,得到17和23,证实了环氯化反应的普遍性。在某些情况下(21和22),分子间偶联优先于氯化反应发生。
