Commercially available tin amine protocol (SnAP) reagents provide a simple approach to the synthesis of a wide variety of saturated N-heterocycles from aldehydes. In this report, we disclose that the copper(II) promoter and hexafluoroisopropanol can be replaced by photocatalytic conditions using Ir[dF(CF3)ppy]2(dtbbpy)PF6 in CH3CN. Continuous flow photochemical conditions provide a clean, scalable
市售的锡胺规程(SnAP)试剂提供了一种从醛合成多种饱和N杂环的简单方法。在此报告中,我们公开了在CH3CN中使用Ir [dF(CF3)ppy] 2(dtbbpy)PF6可以通过光催化条件代替铜(II)助催化剂和六氟异丙醇。连续流动的光化学条件提供了一种清洁,可扩展的方法,用于从醛原料中提取有价值的产品,包括吗啉,哌嗪,硫代吗啉,二氮杂苯并恶唑烷。
