A series of triazolium salts has been synthesized from d-camphor and found to be efficient catalysts for intramolecular crossed aldehyde-ketone benzoin reactions, affording alpha-ketols bearing a quaternary carbon center with up to 93% ee.
已从d-樟脑合成了一系列三唑鎓盐,发现它们是分子内交叉醛-酮安息香反应的有效催化剂,可提供带有高达93%ee的季碳中心的α-酮醇。
