The Abramov reaction, a base-catalyzed nucleophilic addition of dialkyl H-phosphonates (phosphites) to carbonyl compounds, was performed with oxidized quinine derivatives as the substrates. Homologous aldehydes obtained from the vinyl group reacted in a typical way which led to α-hydroxyphosphonates, first reported compounds containing a direct P–C bond between the quinine carbon skeleton and a phosphorus atom. For the C9 ketones a phosphonate–phosphate rearrangement, associated with a tandem elimination of the piperidine fragment, was evidenced.
Abramov反应是一种碱催化的二烷基H-磷酸酯(磷酸酯)亲核加成到羰基化合物的反应,使用氧化的奎宁衍生物作为底物。从乙烯基团获得的同系物醛以典型的方式反应,导致α-羟基磷酸酯,这是首次报道的含有奎宁碳骨架和磷原子之间直接P-C键的化合物。对于C9酮,证明了磷酸酯-磷酸酯重排反应,伴随着哌啶基团串联消除。
