New route to 1-formylalkylphosphonates using diethyl trichloromethylphosphonate as a precursor

Résumé

Diethyl trichloromethylphosphonate 1 and chlorotrimethylsilane were converted in a threestep sequence by BuLi into α−phosphorylated α−silylated α−substituted carbanions 4. On reaction with ethyl formate in the presence of chlorotrimethylsilane they give transient silylated acetals 8 which are readily hydrolysed in acid medium into 1formylalkylphosphonates 7 which are isolated in good yields.
