describes the development of an enantioselective C-N bond-forming reaction to produce 1,2,3,4-tetrahydroisoquinoline-derived cyclic aminals catalyzed by chiral phosphate anions. Central to the success of this goal was the design of a library of 3,3'-triazolyl BINOL-derived phosphoric acids capable of forming attractive hydrogen-bonding interactions with the peptide-like substrate. We envision this work will
本报告描述了对映选择性 CN 键形成反应的发展,以产生由手性磷酸根阴离子催化的 1,2,3,4-四氢异喹啉衍生的环胺。这一目标成功的核心是设计了一个 3,3'-三唑基 BINOL 衍生的磷酸库,能够与肽样底物形成有吸引力的氢键相互作用。我们设想这项工作将提供一种替代传统策略的方法,即增加催化剂空间体积以提高 BINOL 衍生磷酸的对映选择性。
