Abstract

Tris (2-methoxyphenyl) bismuthane works as both a mild dehydrating agent and a good template for macrocyclic ester synthesis; prolonged heating of the bismuthane with a dicarboxylic acid anhydride and a glycol in toluene under reflux afforded the corresponding macrocyclic 1: 1 diester in moderate to good yields, together with a small amount of a macrocyclic 2: 2 tetraester.
