A new synthetic route to coumarinyloxyaldehydes starting from hydroxycoumarins is presented; these compounds, useful intermediates in the preparation of natural products such as geiparvarin and psoralens, are now available in excellent yields with a simple workup procedure. Moreover the reported route has been applied to dihydroxycoumarins.
提出了一种从羟基香豆素开始合成香豆素氧基醛的新方法。这些化合物是制备天然产物(如geiparvarin和补骨脂素)中有用的中间体,现在可以通过简单的后处理程序以高收率获得。此外,所报道的途径已经应用于二羟基香豆素。
