Catalyst-Free and Selective C-N Bond Functionalization: Stereospecific Three-Component Coupling of Amines, Dichloromethane, and >P(O)H Species Affording α-Aminophosphorus Compounds

Catalyst-free and selective C-N bond functionalization has been achieved through three-component coupling of amines, dihalomethane, and >P(O)H species. This reaction takes place stereospecifically with retention of configuration at phosphorus, which can produce various new optically active phosphorus analogues of α-amino acids.

Synthesis of new organophosphorus-substituted mono-and bis(trimethylsilyl) amines with pch2n fragments and their derivatives

Convenient procedures for the synthesis of new organophosphorus-substituted monoand bis(trimethylsilyl)amines with PCH2N moiety are proposed, starting from trimethylsilyl esters of organophosphorus acids, as well as 1,3,5-trialkylhexahydro-1,3,

Synthesis of phosphorus-substituted dialkylamides of organophosphorus acids, containing PCH2NP fragments

Reactions of [N-(trimethylsilyl)aminomethyl]phosphonates with organophosphorus acid chlorides was studied, which allowed to develop convenient synthetic approaches to novel phosphorus-substrituted dialkylamides of organophosphorus acids, including a PCH2NP fragment. Certain properties of the resulting compounds are presented. 2004 MAIK "Nauka/Interperiodica".
