    未脱气溶液中-酮酯的 Norrish II 型光裂解控制香料醛和酮的释放
    摘要:
    伯醇或仲醇的烷基或芳基 α-酮酯在 350 – 370 nm 的辐照下从中间三重态分解为极性和非极性溶剂中的醛或酮。通过在氧气存在下使用氙灯或紫外线灯以及户外阳光进行光辐照,研究了这些酮酯作为控制释放香料醛和酮的释放系统的用途。辐照溶液的系统 GC/MS 分析表明,在这些条件下,酯侧链的所需 Norrish II 型断裂是大多数情况下的主要反应途径。从烷基酮酯的烷基侧链中提取 γ-H,以及分子内Paterno-Buchi 反应或不同香茅基α-酮酯中烯烃官能团的环氧化被确定为最重要的副反应。一些实验结果已经在从头算和密度泛函计算的基础上进行了合理化。发现(环己基)氧代乙酸酯和氧代(苯基)乙酸酯是所需香料应用的最合适的前体。

    The present invention describes a fragrance delivery system which releases fragrant aldehydes or ketones and/or fragrant compounds containing an olefin function upon exposure to light. This system comprises &agr;-keto esters of formula in which R′* and R″* have the meaning as defined in the application and which are generally, in case of R′*, an alkyl group carrying an abstractable hydrogen in &ggr;-position relative to the &agr;-keto function and carrying a moiety from which is derived a fragrant compound containing an olefin function, and, in case of R″*, the organic part of a primary or secondary alcohol from R″*OH which is derived a fragrant aldehyde or ketone.
    该发明描述了一种香气释放系统,该系统在受光照射时释放香醛或酮香味化合物和/或含有烯烃功能的香味化合物。该系统包括具有以下结构的α-酮酯:其中R′*和R″*的含义如申请中所定义,并且通常情况下,对于R′*,是一种携带可被提取氢的烷基基团,在α-酮功能相对位置上携带一个基团,该基团来源于含有烯烃功能的香味化合物,并且对于R″*,是从R″*OH中导出香醛或酮的初级或次级醇的有机部分。
