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

aminomethylation of the several esters of hypophosphorous acid using chloro-, alkoxy-, and amino-substituted methylamines of various structure is proposed as convenient method for the synthesis of newfunctionalizedaminomethylphosphonites and bis(aminomethyl)phosphinates. Also O,O-diethyl(pivaloyl)phosphonite is successfully applied in the aminomethylation as a synthetic analog of unstable diethoxyphosphine.

An efficientsynthesis of 7-membered Aza-sultams bearing heterofused amino-1,2,4-thiadiazepine framework have been developed. Functional group pairing strategy using ambiphilic building blocks such as 1H-azole-2-carbonitrile and N-(chloromethyl)-N-methylmethanesulfonamide in the two-step base-mediated reaction sequence was described. The synthetic utility of the obtained Aza-sultams was demonstrated
Synthesis of phosphonamides of methane- and benzenesulfonic acids bearing the P—C—N fragments

Preparative synthetic procedures towards new phosphorus-containing benzenesulfon-amides were elaborated. The synthesis is involved the reactions of trivalent phosphorus acids with high reactive N-methyl-N-chloromethylsulfonamide, phosphorylated methylamines bearing the NH and NSi groups, and methane-and benzenesulfonyl chlorides.
