The Lewis acid catalyzed (BF3·Et2O, CuCl, AcOH) one-pot three-component cyclocondensation of urea with C-glycosylated aldehydes and β-keto esters (Biginelli reaction) in a combinatorial manner afforded three different series of 3,4-dihydropyrimidin-2(1H)-ones bearing C-glycosyl moieties at C4, C6, and at both C4 and C6.
路易斯酸通过C糖基化醛和β-酮酸酯的双锅法三联催化尿素(BF 3 ·Et 2 O,CuCl,AcOH)三组分缩合反应,得到三个不同的3系列在C4,C6以及在C4和C6两者处带有C-糖基部分的4-二氢嘧啶-2(1 H)-1 。
