The diastereoselective Bu4NCN-catalyzed addition of TMSCN to cyclic α,β-epoxyketones has been considered. Good diastereoselectivities were found, depending on the ring size of the starting material. Computational studies account for the observed diastereoselectivities. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
已经考虑了非对映选择性 Bu4NCN 催化的 TMSCN 与环状 α,β-环氧酮的加成。发现了良好的非对映选择性,这取决于起始材料的环大小。计算研究解释了观察到的非对映选择性。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
