A simple and efficient synthesis of dioxazaphosphinin-2-ones has been developed by the cyclisation of 2-hydroxy-1,2-diphenylethanoneoxime with phosphorus oxychloride in the presence of triethylamine in dry THF to afford the corresponding monochloride. In the next step, subsequent reaction of monochloride with different amines at 50-60 ̊C for 2-3 hours resulted in the formation of the title comp...

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...
