two-step procedure for the synthesis of fused chromenone derivatives was developed. Reduction of the obtained in the Meerwein arylation reaction aryl- and thienylquinones allowed to construct 6H-benzo[c]chromene-6-ones and 4H-thieno[2,3-c]chromen-4-one in a more cost- and time-effective manner in comparison with already known methods. The obtained products have provided a new entry to chromenone derivatives
摘要 开发了合成稠合色酮衍生物的方便的两步法。减少在 Meerwein 芳基化反应中获得的芳基-和噻吩基醌允许以更多的成本和时间构建 6H-benzo[c]chromene-6-ones 和 4H-thieno[2,3-c]chromen-4-one - 与已知方法相比的有效方式。获得的产品为色酮衍生物提供了一个新的入口。图形概要
