Stereochemically and functionally rich polycyclic compounds are obtained by the first crossed aldehyde-ketone benzoin reaction in excellent yield under mild reaction conditions (5-20 mol % thiazolium salt, 10-70 mol % DBU, tBuOH, 40 degrees C, 30 min). This novel catalytic methodology offers a convenient approach to sophisticated molecular architectures useful for the stereocontrolled construction
在温和的反应条件下(5-20 mol% 噻唑鎓盐,10-70 mol% DBU,tBuOH,40 摄氏度,30 分钟),通过第一次交叉醛-酮安息香反应获得立体化学和功能丰富的多环化合物。这种新颖的催化方法为复杂的分子结构提供了一种方便的方法,可用于多环化合物的立体控制构建以及蒽醌和萘醌的完全区域控制合成。
