Synthesis of vinyl azides

Recent Literature

The nucleophilic addition of sodium azide to 1,2-allenyl esters regio- and stereoselectively generates vinyl azides in excellent yields. A sequential reaction for the synthesis of pyrroles using 1-allyllic 1,2-allenyl esters as substrates is developed on the basis of a domino process involving nucleophilic addition, cycloaddition, denitrogenation, and aromatization.
