Abstract

A palladium‐catalyzed multicomponent reaction of propargylic amines, alkynyl bromides and cesium hydrogen carbonate to access oxazolidinones is reported. In contrast to previous reports, only a slight excess of cesium hydrogen carbonate is used as a surrogate of carbon dioxide. The reaction gives access to oxazolidinones bearing alkyl‐ and aryl polysubstituted enynes in good yield and very high E stereoselectivity. [ABSTRACT FROM AUTHOR]
