摘要
A ring-expansion reaction of 2H-azirine with trifluoroacetic anhydride for the synthesis of 2-(trifluo-romethyl)oxazoles is disclosed. The reaction features readily available reactants, relatively mild condi-tions, and high yields of products. The generated 2-(trifluoromethyl)oxazole core could be easily converted into 3-(trifluoromethyl)-1,2,4-triazines through hydrazinolysis reaction.(c) 2022 Elsevier Ltd. All rights reserved.
