Boric Acid Catalyzed Methyl Esterification of Sugar Acids
, 2014 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-
