An Unprecedented Pd-Catalyzed, Water-Promoted Sequential Oxidative Aminocarbonylation−Cyclocarbonylation Process Leading to 2-Oxazolidinones
摘要:
An unprecedented, PdI2-catalyzed, sequential oxidative aminocarbonylation-cyclocarbonylation process, leading to 2-oxazolidinone derivatives 3 in good to excellent yields starting from readily available alpha,alpha-disubstituted 2-ynylamines 1 and secondary amines 2, is reported. In the case of an alpha-monosubstituted substrate, the initially formed 2-oxazolidinone derivative underwent shift of the double bond to give a 3H-oxazol-2-one derivative in excellent isolated yield.
