Heterogeneous catalytic hydrogenation of unsaturated 1,2,4-trioxanes derived from β-ionone-type dienones has been investigated. Our studies revealed a versatile reactivity of trioxanic substrates that led to the development of reaction methodology for the selective manipulation of the alkene and peroxide functionalities. Depending on the catalytic system used, divergent reaction pathways can be controlled
已经研究了衍生自β-紫罗兰酮型二烯酮的不饱和1,2,4-三恶烷的非均相催化氢化反应。我们的研究揭示了三恶烷底物的多功能反应性,从而导致了反应方法的发展,用于选择性地操纵烯烃和过氧化物官能团。取决于所使用的催化体系,可以控制不同的反应途径以提供相应的饱和1,2,4-三恶烷或呋喃结构。提出了一种机械合理化,其解释了这些杂环的还原行为。
