The development of an efficient and sustainable synthetic route for formaldehyde production from renewable feedstock, especially in combination with a subsequent transformation to straightforwardly construct valuable chemicals, is highly desirable. Herein, we report a novel manganese-catalyzed dehydrogenative cyclization of methanol as a formaldehyde surrogate with a variety of dinucleophiles for facile
开发一种高效且可持续的从可再生原料生产甲醛的合成路线,尤其是结合随后的转化以直接构建有价值的化学品是非常可取的。在此,我们报告了一种新型的锰催化甲醇脱氢环化反应,作为甲醛替代物,其具有多种亲核试剂,可方便地合成N-杂环化合物。通过催化甲醇脱氢原位产生的甲醛可以被多种双亲核试剂选择性地捕获,以避免几种可能的副反应。这种转化的实用性通过其成功应用于合成13 C-标记的N-杂环使用13 CH 3 OH 作为容易获得的13 C-同位素试剂。
