Abstract

A mild and highly selective hydrosilylation method was employed to synthesize five novel well-defined Janus ring siloxanes bearing terpenes and terpenoids, which are the main bioactive components of essential oils. The characterization of these new bio-sourced molecular materials, derived from hydrosilyl-substituted all--cyclotetrasiloxane, was conducted through comprehensive analyses using multinuclear NMR, infrared spectroscopy, elemental analysis, and mass spectroscopy. The thermal stability of the newly synthesized Janus rings was investigated, and the siloxane skeleton was shown to confer an enhanced thermal stability compared with free terpenes and terpenoids.

摘要

采用一种温和且高度选择性的硅氢化方法合成了五种新型的、结构明确的含萜类和萜类化合物的Janus环硅氧烷，这些化合物是香精油的主要生物活性成分。对这些源自氢化硅取代的全环四硅氧烷的新型生物源分子材料进行了表征，通过多核核磁共振、红外光谱、元素分析和质谱等综合分析手段来完成。研究了新合成的Janus环的热稳定性，结果表明，与游离萜类和萜类化合物相比，硅氧烷骨架赋予了其更高的热稳定性。
