The total synthesis of macrolides, a group of antibiotics having a variety of large lactone rings, has been one of the most important subjects in the recent synthetic elaborations on natural products. In the present review are described several new lactonization methods which have been used in the syntheses of this class of compounds and some new esterification methods developed in our laboratory, one of which, the method using the mixed carboxylic 2, 4, 6-trichlorobenzoic anhydrides, has been successfully applied to the synthesis of methynolide.
