  The preparation of Wang resin bound alpha-diazo-beta-ketoesters is described. These highly useful intermediates were used for the synthesis of a series of heterocycle libraries, which were obtained from the resin using TFA cleavage. In addition, a novel route for the synthesis of oxazolones using an N-H insertion strategy is disclosed. (c) 2005 Elsevier Ltd. All rights reserved.
