Samarium(II) diiodide-mediated intermolecular aldol type reactions of phenacyl bromides with carbonyl compounds
摘要:
Intermolecular aldol type reactions of phenacyl bromides with various carbonyl compounds mediated by samarium(II) diiodide afford beta-hydroxy ketones in moderate to good yields. The addition of N,N,N',N'-tetramethylethylenediamine or diethylaluminium chloride resulted in better yields in some reactions.

Described herein are compounds, methods of making such compounds, pharmaceutical compositions and medicaments containing such compounds, and methods of using such compounds to treat or prevent diseases or disorders associated with the enzyme ceramide galactosyltransferase (CGT), such as, for example, lysosomal storage diseases. Examples of lysosomal storage diseases include, for example, Krabbe disease and Metachromatic Leukodystrophy.

The non-conventional hydrolysis of mixtures of diastereoisomeric α-bromo acetals, available in high yields, high diastereomeric excesses, and in large amounts, allows the synthesis and the full characterization of enantiomerically pure (2S)- and (2R)-bromoalkyl aryl ketones. The developed methodology represents the first route to enantiomerically pure 2-bromoalkyl aryl ketones of (2R) and (2S) configurations.
