Tris(2-methoxyphenyl)bismuthane as a Dehydrating Agent with High Template Ability: an Efficient Single-step Synthesis of Macrocyclic Diesters from Diacid Anhydrides and Glycols

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.
