The two-step acidic hydrolysis of α-hydroxybenzylphosphonates and a few related derivatives was monitored in order to determine the kinetics and to map the reactivity of the differently substituted phosphonates in hydrolysis. Electron-withdrawing su

A highly enantioselective synthesis of dialkyl α-hydroxyphosphonates achieved by a oxazaborolidine catalyzed reduction with catecholborane starting with α-ketophosphonates is described. Both α-aryl- and α-alkylketophosphonates were reduced using

5-Methylisatin ( 1b) reacts with TAP ( 4a–c) and/or DAP ( 3a-c) to give the respective dialkyl α-hydroxyphosphonates (8a-c). Isatin-monoxime ( 5a) and 5-methyl isatin-monoxime ( 5b) react with alkyl phosphites to give dialkyl 2-oxo-indolyl phospho
