Nucleophilic addition of trimethylsilyl esters of tricoordinate organophosphorus acids to various functionalized aldehydes with vinyl, aryl, and heterocyclic fragments is proposed as a convenient method for the synthesis of new 1-trimethylsiloxysubstituted alkylphosphonites and their derivatives at mild conditions. Also the new functionalizedderivatives of these phosphonites, including amino groups

Hydrolysis of 3-pyridylmethyl(amino)phosphonates by means of 20% aq. hydrochloric acid gave corresponding 3-pyridylmethyl(amino)phosphonic acids, as expected. However, hydrolysis of 2- and 4-pyridylmethyl(amino)phosphonates led to decomposition of the phosphonates with a cleavage of CP bond and formation of the corresponding amines. The leaving phosphorus moiety was identified as phosphoric acid.

The convenient syntheses of new aryl-substituted hydroxymethylphosphonic and methylenediphosphonic acids from the aromatic aldehydes, their derivatives, and phosphorous acid esters in the presence of the effective catalysts (trimethylsilyl trifluoromethanesulfonate, zinc chloride, and cadmium iodide) were developed.

Simple and versatile synthetic procedures towards new aryl-substituted hydroxymethylphosphonic and methylenediphosphonic acids via reactions of either aromatic aldehydes or their derivatives with phosphites were elaborated.

method B2). However, in this case, bioconversion was not enantioselective – products: amino- and hydroxyderivative were obtained as racemic mixtures. Both biocatalysts were also tested towards the scaling so other biocatalytic procedures were introduced - with immobilized fungal mycelium. In case of Rhodotorula mucilaginosa this approach failed (data not shown) but Penicillium funiculosum turned out to be
