Abstract

Boric acid catalyzes methyl esterification of certain sugar acids (sialic acid, deaminated neuraminic acid) and related natural products (quinic acid) quite cleanly in some cases. However, closely related sugar acids (glucuronic acid, 3-deoxy-d-manno-oct-2-ulosonic acid) failed to esterify under the same conditions. Factors governing this dichotomy are discussed.
