are released. Since β-mercaptoketones are potent natural aroma compounds occurring in many fruits, herbs and flowers, the discovery of an enzyme-independent molecular precursor for this class of high-impact molecules is of practical importance. Moreover, the formation of β-diketones and aldehydes by concomitant oxidation at the α-sulfur-position enhances the versatility of this class of aroma precursors
β-烷基硫代烷酮在环境空气中缓慢降解的深度顶空分析导致发现了一种新的 δ-裂解途径,通过该途径释放 β-巯基酮。由于 β-巯基酮是存在于许多水果、草药和花卉中的强效天然香气化合物,因此发现此类高影响分子的不依赖酶的分子前体具有实际意义。此外,通过在 α-硫位处伴随氧化形成 β-二酮和醛增强了此类香气前体的多功能性。提出了一种机制模型,该模型表明氧化降解是通过最初形成的过亚砜的新型普默雷型重排发生的。
