enantioconvergent access to chiral N-heterocycles directly from simple racemic diols and primary amines, through a highly economical borrowing hydrogen annulation. The identification of a chiral amine-derived iridacycle catalyst was the key for achieving high efficiency and enantioselectivity in the one-step construction of two C–N bonds. This catalytic method enabled a rapid access to a wide range of
我们提出了一种通过高度经济的借氢环化直接从简单的外消旋二醇和伯胺获得手性N -杂环的对映收敛途径。鉴定手性胺衍生的iridacycle催化剂是在一步构建两个C-N键中实现高效和对映选择性的关键。这种催化方法能够快速获得各种不同取代的富含对映体的吡咯烷,包括有价值药物(如阿替卡普兰和 MSC 2530818)的关键前体。
