<i>N</i>-1-Alkenyl-<i>N,S</i>-Diacyl-2-Aminobenzenethiols (Enamides) by Ring-Opening of 2,3-Dihydro-1,3-benzothiazoles with Aliphatic Carboxylic Anhydrides
The enamides 3 and 4 are obtained in good yields by treatment of 2,3-dihydro-1, 3-benzothiazoles 1 or N-acylderivatives 2 with aliphatic acid anhydrides.
