trivalent organophosphorus acids to various functionalized acrylates and their cyclic analogues is proposed as convenient methods for the synthesis of new 2-trimethylsiloxycarbonyl-substituted alkylphosphonites and their derivatives under mild conditions. Also the new functionalized derivatives of these phosphonites, including amino, amido, and amino acids fragments as well as certain properties of these

A convenient synthesis of functionalized furan-containing phosphonous and phosphinic acids has been developed. The radical addition of bis(trimethylsiloxy)phosphine to 2-vinylfuran and trimethylsilyl 3-(2-furyl)acrylate proceeds regioselectively to afford new 2-furyl-substituted alkylphosphonites, the subsequent aminomethylation and carboxyethylation of which give various target phosphinic acids.
