Herein is described a versatile and broad synergistic strategy for expansion of chemical space and the synthesis of valuable molecules (e.g. carbocycles and heterocycles), with up to three quaternary stereocenters, in a highly enantioselective fashion from simple alcohols (31 examples, 95:5 to >99.5:0.5 e.r.) using integrated heterogeneous metal/chiral amine multiple relay catalysis and air/O2 as the terminal
本文描述了一种通用的,广泛的协同策略,用于扩展化学空间和合成有价值的分子(例如碳环和杂环),并具有多达三个四级立体中心,以对映体的方式从简单的醇类中高度选择性(31例,95:5至> 99.5:0.5 er),使用集成的多相金属/手性胺多重中继催化,并将air / O 2用作末端氧化剂。一种新型的高度1,4-选择性多相金属/胺共催化的烯醛加氢反应也被添加到中继催化序列中。
