4-Azidotetronic Acids: A New Class of Azido Derivatives
摘要:
4-Azidotetronic derivatives bearing different substituent groups on the carbon atom in position 3 were easily obtained by reaction of the corresponding 4-bromotetronic compounds with sodium azide in methanol at room temperature.

A new amide synthesis strategy based on a fundamental mechanistic revision of the reaction of thioacids and organic azides is presented. The data demonstrate that amines are not formed as intermediates in this reaction. Alternative mechanisms proceeding through a thiatriazoline intermediate are suggested. The reaction has been applied to the preparation of simple and architecturally complex amides
