A wide range of 5-substituted thiazoles are easily accessible via cross coupling of thiazolyl triflates. These activated thiazoles can be obtained by Ugi reactions using thioacids (thio-Ugi-reaction) and subsequent cyclisation of the endo thiopeptides formed with triflic anhydride. In addition, cyclisations with acyl halides give rise to 5-acyloxysubstituted derivatives.
