    Description / Table of Contents: Deamination of β- and γ-Amino AlcoholsNitrous acid deaminations of the β-amino alcohols 2 and 12 afford 1,2-diols as well as ketones by pinacolic rearrangement. Both types of products arise with predominant inversion of configuration. Stereochemical studies and isotopic labeling reveal that formation of the diols involves an oxygen shift, presumably via oxirane intermediates. Deamination of the γ-amino alcohol 37 induces, in part, sequential rearrangements to give products also obtained from 12, but in different proportions and enantiomeric purities. Conformational control provides a reasonable explanation of our results.
    Notes: Die Desaminierung der β-Aminoalkohole 2 und 12 mit salpetriger Säure ergibt 1,2-Diole und durch Pinakolumlagerung Ketone. Beide Produkte werden mit überwiegender Konfigurationsumkehrung gebildet. Stereochemische Untersuchungen und Isotopenmarkierungen zeigen, daß die 1,2-Diole unter Sauerstoffverschiebung entstehen, wahrscheinlich über Oxiran-Zwischen-stufen. Desaminierung des γ-Aminoalkohols 37 führt zum Teil zu Mehrfachumlagerungen, aus denen die gleichen Produkte wie aus 12 hervorgehen, jedoch in unterschiedlicher Menge und enantiomerer Reinheit. Unsere Ergebnisse lassen sich durch konformative Kontrolle plausibel deuten.
