comprehensive study into the Cp 2 TiCl-mediated reductive epoxide ring opening using either water as a hydrogen source or deuterium oxide as a deuterium source. The remarkable chemical profile of this reaction allows access to alcohols with anti-Markovnikov regiochemistry from different epoxides. The use of D 2 O as a deuterium source leads to an efficient synthesis of β-deuterated alcohols, including a deuterated
我们描述了使用水作为氢源或使用氧化氘作为氘源的 Cp 2 TiCl 介导的还原性环氧化物开环的综合研究。该反应的显着化学特征允许从不同的环氧化物中获得具有抗马尔科夫尼科夫区域化学的醇。使用 D 2 O 作为氘源可有效合成 β-氘化醇,包括酪醇的氘化样品,酪醇是一种包含在橄榄叶中的生物活性化合物,已成功用作食品分析中的内标.
