An efficient boric acid-mediated preparation of α-hydroxyamides

An efficient methodology for the preparation of α-hydroxyamides via boric acid-mediated addition of isonitriles onto aldehydes has been developed. The reaction of isonitriles with α-boronobenzaldehyde takes place under intramolecular catalysis conditions to provide functionalized benzoxaboroles.
