We describe here a protocol for alkylation of quinazolinones with a series of primary or secondary alcohols under metal-free conditions. A class of quinazolinone derivatives were obtained in 31%–97% yield with good functional group tolerance. This protocol provides chemists a direct and effective way to obtain bioactive quinazolinone derivatives.
我们在这里描述了在无金属条件下用一系列伯醇或仲醇对喹唑啉酮进行烷基化的方案。得到一类喹唑啉酮衍生物,收率31%~97%,具有良好的官能团耐受性。该方案为化学家提供了获得生物活性喹唑啉酮衍生物的直接有效的方法。
