Abstract Tandem reactions between β-iodoazides and propargyl alcohols under mild conditions are presented, providing a general and convenient method for the synthesis of 6,7-dihydro-4H-[1,2,3]triazolo[5,1-c][1,4]oxazines. The advantages of this method are its simple operation, high efficiency and high product yields (80–95%).
