yields of the corresponding β-iodofurans. The necessary precursors are available from a number of different approaches, notably regioselective bis-hydroxylation of conjugated enynes and the addition of acetylides to α-hydroxy carbonyl groups. The initial iodofurans can be homologated using a number of strategies, ranging from various transition metal-catalysed couplings to halogen-metal exchange and subsequent

Iodocyclisations of 3-alkyne-1,2-diols, obtained from acetylides and a-hydroxy-ketones or esters, give generally excellent yields of beta -iodofurans by 5-endo-dig cyclisation followed by dehydration. (C) 2001 Elsevier Science Ltd. All rights reserved.

The present invention relates to methods for screening, identifying, and/or quantifying modulators of amyloid and/or aggregates, fibrils or components thereof, in particular modulators of amyloid β-peptide (Aβ) or Aβ fibrils. Aspects of the invention provide methods for screening putative modulators against an Amyloid target, in particular an Aβ target, so as to determine which modulators bind to or interact with the target, or interfere with the interaction of an indicator agent and the target. Particular aspects of the invention employ mass spectrometric methods for the screening of an Amyloid target against compound libraries, in particular mixtures of compounds or combinatorial libraries.

A gold-catalyzedsynthesis of an important building block, 1-(furan-3-yl)-1,2-diones, from easily available starting materials under mild reaction conditions was reported. Preliminary mechanistic investigation indicated that water was involved as a reactant in the reaction serving as an oxygen source.
