A one-pot approach using palladium-copper as catalyst has been developed for the synthesis of morpholines fused with 1,2,3-triazole. Good regioselectivity, mild reaction conditions, high yields and short reaction time are the hallmarks of this method.
Synthesis of 6,7-dihydro-4<i>H</i>-[1,2,3]triazolo[5,1-<i>c</i>][1,4]oxazines <i>via</i> tandem reactions of <i>β</i>-iodoazides with propargyl alcohols
Abstract Tandem reactions between β-iodoazides and propargylalcohols 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%).
