    摘要: 5-formyl-2-furylboronic acid is produced by a) adding a base to a composition containing a boric acid ester and 2-furaldehyde, thereby obtaining a reaction mixture and protecting the formyl group of said 2-furaldehyde with a protective group, b) working-up of the reaction mixture in an acidic medium, and c) isolating of the 5-formyl-2-furylboronic acid.
