2‐amino alcohols from trans‐1,2‐azido alcohol precursors was developed. The key step is highlighted by the stereoselective reduction of the cyclic α‐alkoxy imines, which could be prepared from the corresponding azides by ruthenium catalysis under photolytic conditions. Remarkably, this unprecedented reaction pathway offers a stereodivergent access to structurally diverse cyclic 1,2‐amino alcohols.
从反式1,2-叠氮基醇的前体开发了一种独特的一锅法合成环状顺式1,2-氨基醇。环状α-烷氧基亚胺的立体选择性还原突显了关键步骤,这可以通过在光解条件下通过钌催化由相应的叠氮化物制备。值得注意的是,这种空前的反应途径提供了结构多样的环状1,2-氨基醇的立体异构途径。
