Abstract
Barton esters were prepared starting from different carboxylic acids loaded on a Wang resin. Light induced fragmentation occurred giving a radical tha t reacted with CBrCl3 to give the corresponding bromides, whereas conjugate addition to electron-poor alkenes proved to be less synthetically useful. The bromides so formed were further functionalised on the resin with differ ent nucleophiles. (C) 2001 Elsevier Science Ltd. All rights reserved.
