solvent-free Passerini-tetrazole threecomponentreaction (PT-3CR) has been developed for the selective synthesis of benzoxaborol-tetrazoles for the first time. The synthetic potential of oxaboroles was demonstrated towards various functionalized tetrazoles, which are otherwise difficult to achieve through conventional PT-3CR from aromatic aldehydes/ketones. The reaction features high practicality, broad

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.
