    摘要:
    2-取代-2,3-二氢-3-邻甲苯基(氯苯基)-4(1 H)-喹唑啉酮1a-j中的芳基与杂环部分之间的立体相互作用产生了对绕芳基C N键旋转的充分限制在室温下可以检测到扭转异构体的存在。非对映异构体的数量和旋转激活的自由能已通过1 H nmr光谱进行了计算。可能由于R 2取代基的优选轴向位置,对于1a-f而言,未观察到A / B比和ΔG≠值的显着变化。1a和1j的比较ΔG ≠ 值允许对过渡态的结构提出假设。

    A simple and efficient protocol for one-pot three-component coupling of isatoic anhydride, amines, and aldehydes in water using magnetically recoverable Fe3O4 nanoparticles is reported. This methodology results in the synthesis of a variety of 2,3-dihydroquinazolin-4(1H)-ones in high yields. The catalyst can be recovered and recycled without a significant loss in the catalytic activity.
