A facile method to obtain an isochromanic structure was achieved by the oxa-Pictet-Spengler reaction using 2-(3',4'-dihydroxy)phenylethanol as starting material. The reaction was performed in very mild conditions on a series of carbonylic compounds. Yields were always satisfactory. (C) 2001 Elsevier Science Ltd. All rights reserved.
