A straightforward synthesis of 5-phenylthiazolamines via coupling of thiourea with phenylacetones, phenylacetophenones and β-tetralone has been developed. Thiourea acts as a substrate and an -bromination shuttle, transferring Br from the brominating reagent, CBrCl3, to the β-carbon of the carbonyl moiety before triggerring a series of steps to form the final product. Isolated yields of 80 to 95

Non-peptidic small molecule SMAC mimetics were designed and synthesized that bind to the BIR3 domain of XIAP using structure-based design. Substituted five-membered heterocycles such as thiazoles and imidazoles were identified that serve as replacements for peptide fragments of the lead. (C) 2004 Elsevier Ltd. All rights reserved.
