Overview

A novel method for the synthesis of trisubstituted oxazoles via a one-pot oxazole synthesis/Suzuki-Miyaura coupling sequence has been developed. One-pot formation of 5-(triazinyloxy)oxazoles using carboxylic acids, amino acids and a dehydrative condensing reagent, DMT-MM, followed by Ni-catalyzed Suzuki-Miyaura coupling with boronic acids provided the corresponding 2,4,5-trisubstituted oxazoles in good yields.
Access to highly substituted oxazoles by the reaction of α-azidochalcone with potassium thiocyanate.
