An easy and mild two-step one-pot reaction allowed the synthesis of functionalized N-triazolyl maleimide.
Next, the addition of propargyl alcohol and propargyl amine to the N-acyliminium ion mediated
by Lewis acid, In(OTf)3, allowed the introduction of a second 1,2,3-triazol ring at position 5 of the amide.
The products in both reactions were achieved in moderate to good yields.
