A. Acyloin Rearrangement An acyloin-type rearrangement is an acid-catalyzed reorganization of α-hydroxy ketones (13.31), also known as acyloins (Scheme 13.14). These acid-catalyzed [1,2]-alkyl migration reactions also can involve other types of molecules, such as glycols (pinacol rearrangement)...
using morita-baylis-hillman adducts as substrates, the curtius rearrangement was performed in a sequence that allowed the synthesis of several hydroxy-ketones (acyloins) with great structural diversity and in good overall yields. these acyloins in turn were easily transformed into 1,2-anti aminoalco...
Both dimethylphenyl- and methyldiphenylsilyllithium were found to be effective, the latter providing greater stereocontrol. The reaction is believed to proceed via Brook rearrangement assisted by expulsion of the adjacent leaving group. A number of acyclic acyloin derivatives were reacted to form the ...
Treatment of acetophenones with thallium(III) nitrate in acidic methanol is shown to result in smooth oxidative rearrangement to give methyl arylacetates in moderate to excellent yields. The scope and limitations of the synthesis have been defined and the mechanism of the transformation studied by...
The 5/7 membered ring system of 6-dehydro derivatives (2, 3, 5 and 6) of grayanotoxin-II (1) was converted to a 6/6 membered ring system (8a and 8b) in consequence of an acyloin rearrangement in alkaline media. The configurations of C3 and C6 of the products (8a and 8b) were ...
