In this letter, we developed a palladium-catalyzed procedure for the cyclocarbonylation of propargyl amines. Benzene-1,3,5-triyl triformate (TFBen) has been explored as the CO source and also as the key promotor. Various substituted 2-oxo-dihydropyrroles were produced in a facile manner in good yields (up to 90%).
在这封信中,我们开发了钯催化的炔丙基胺环羰基化的方法。苯甲酸1,3,5-三甲酸三乙酯(TFBen)已被研究用作CO的来源,也是主要的促进剂。以容易的方式以良好的产率(高达90%)生产了各种取代的2-氧代-二氢吡咯。
