Silanediol and copper catalysis are merged, for the first time, to create an enhanced Lewis acid catalyst system for enantioselective heterocycle functionalization. The promise of this silanediol and copper catalyst combination is demonstrated in the enantioselective addition of indoles to alkylidene malonates to give rise to the desirable adducts in excellent yield and high enantiomeric excess.

硅烷二醇和铜催化首次合并,以创建用于对映选择性杂环官能化的增强的路易斯酸催化剂体系。这种硅烷二醇和铜催化剂组合的前景在吲哚向亚烷基丙二酸酯的对映选择性加成中以优异的产率和高的对映体过量产生了所需的加合物得到了证明。从这些研究中,基于1,1'-二-2-萘酚(BINOL)的硅烷二醇成为一种助催化剂。还讨论了它们在反应途径中的潜在作用。
