First general one-pot direct trans-dihydroxylation of electron-deficient α,β-unsaturated amides was developed. Trans-1,2-diols were produced, rather than cyclizing nitrogen-containing heterocycles by using inorganic oxone as a dual-role reagent in water. This reaction allowed operational simplicity, switchable selectivity, broad substrate scope, no metal pollution and organic waste generation.
开发了第一个缺电子α , β-不饱和酰胺的通用一锅法直接反式二羟基化反应。通过使用无机过硫酸氢钾作为水中的双作用试剂来生产反式-1,2-二醇,而不是环化含氮杂环。该反应操作简单、选择性可切换、底物范围广泛、无金属污染和有机废物产生。
