An efficient boric acid-mediated preparation of α-hydroxyamides
摘要:
An efficient methodology for the preparation of alpha-hydroxyamides via boric acid-mediated addition of isonitriles onto aldehydes has been developed. The reaction of isonitriles with alpha-boronobenzaldehyde takes place under intramolecular catalysis conditions to provide functionalized benzoxaboroles. (c) 2009 Elsevier Ltd. All rights reserved.
