New α-amino acetals containing a phosphonate or phosphine oxide group were synthesized by the Kabachnik-Fields reaction in the ternary system amino acetal-paraformaldehyde-dialkyl phosphonate (or dialkylphosphine oxide). Condensation of dialkyl (2,2-dimethoxyethylamino)methylphosphonates with resorcinol and its derivatives in ethanol in the presence of hydrochloric acid, apart from the corresponding 2,2-bis(polyhydroxyphenyl) ethylammonium salts, gave 2,5-bis(polyhydroxyphenyl)-1,4-bis[(dialkoxyphosphoryl)methyl]-piperazines. Dialkyl[(2,2-dimethoxyethylamino)methyl]phosphine oxides (Alk = C8H17, C10H21) did not react with resorcinol derivatives under similar conditions, and analogous ammonium salts were obtained by heating the reactants in boiling trifluoroacetic acid. 相似文献

Reaction of adenine and 9-[2-(1,3-dioxolan-2-yl)ethyl]-9H-purine-6-amine with ethylidene-1,1-bisphosphonates resulted in the formation of new purine bases containing ethylidene-1,1-bisphosphoryl groups.

Adenosine derivatives containing a 2,2-bis(diethoxyphosphoryl)ethyl or 2,2-diphosphonoethyl group on the amino nitrogen atom were synthesized for the first time by reaction of 5′-chloro-5′-deoxy- and 5′-hydroxy-2′,3′-isopropylideneadenosine with tetraethyl ethene-1,1-diylbis(phosphonate) or tetrakis(trimethylsilyl) ethene-1,1-diylbis(phosphonate). 相似文献

New phosphorylated aminoacetal has been synthesized by the Kabachnik–Fields reaction; its reactivity has been studied in acid‐catalyzed condensation with linear polyphenols (2‐methylresorcinol, resorcinol, pyrogallol) and the Mannich reaction with macrocyclic polyphenol (calix[4]resorcinol). It has been determined for the first time that acid‐catalyzed reaction of phosphorus‐containing acetal with resorcinol and its derivatives in ethanol in the presence of hydrochloric acid gives new phosphorylated piperazines in addition to the compounds of diarylmethane series. Condensation of macrocyclic polyphenol (calix[4]resorcinol) with formaldehyde and N‐((dihexylphosphoryl)methyl)‐2, 2‐dimethoxyethylamine (the Mannich reaction) has resulted in novel tetrasubstituted calixarene containing aminophosphine oxide and acetal groups on the “upper rim” of molecule. 相似文献

Reactions of calixarenes with methylaminoacetaldehyde dimethyl acetal and formalin gave Mannich bases with the calixarene
platform. It was found by dielcometric titration that calix[4]resorcinols with acetal groups in the aminomethyl fragment form
head-to-head supra-molecular aggregates in chloroform at low concentrations.
