Action of trialkyl phosphites on 10-bromoanthrone and methyleneanthrone

Arbuzov B.; Zoroastrova V.; Ibragimova N. (1967)

1. Trialkyl phosphites undergo a Perkow reaction with 10-bromoanthrone with the formation of an anthryl dialkyl phosphite. 2. Triethyl phosphite adds to methyleneanthrone with the formation of diethyl 9-ethoxy-10-anthryl ...
Biologically active oligosaccharides from pectins of Pisum sativum L. seedlings affecting root generation

Zabotina O.; Ibragimova N.; Zabotin A.; Trofimova O.; Sitnikov A. (2002)

Two physiologically active oligosaccharide fractions were isolated from pectin of Pisum sativum L. cell wall after its partial acid hydrolysis. These fractions displayed stimulating and inhibiting effects on root formation ...
Comparative analysis of escherichia coli strain plasmid DNA profile, isolated from normal and malignant intestinal epithelium of the patients with colorectal cancer

Nguen N.; Ibragimova N.; Gataullin I.; Vafin R.; Ilynskaya O. (2015)

Optionally cultured aerobic bacteria were isolated from the biopsy materials from the colorectal cancer patients (CCP). The species belonging was determined using MALDI-TOF mass spectrometry. Escherichia coli bacteria were ...
Derivatives of phosphorus acids and 2-chloro-2-propen-1-ol

Arbuzov B.; Zoroastrova V.; Ibragimova N.; Neklesova I.; Mazur B.; Kudrina M.; Egorova N.; Iraidova I. (1967)

1. A number of derivatives of phosphorus acids and 2-chloro-2-propen-l-ol were prepared, and some of their chemical and biological properties were studied. 2. The 2-chloroallyl phosphorus derivatives synthesized are contact ...
Epoxidation of diastereomeric 4-(α-hydroxyethyl)-3-carenes

Isaeva Z.; Ibragimova N.; Povodyreva I.; Timoshina T. (1979)

Epoxldation of diastereomeric 4-(hydroxyethyl)- and 4-(acetoxyethyl)-3-carenes stereospecifically gives trans isomers of the corresponding epoxides. © 1979 Plenum Publishing Corporation.
Hydrolysis of 4-acetyl-3α, 4α-epoxycarane

Arbuzov B.; Ibragimova N.; Povodyreva I. (1980)

The acid hydrolysis of 4-acetyl-3α,4α-epoxycarane proceeds with opening of the oxide ring at the carbon atom not attached to an electronegative substituent to give the diol 4β-acetyl-3β, 4α-caranediol. © 1980 Plenum ...
Isomerization of 3 β-acetyl-α-3,4-epoxycarane

Arbuzov B.; Isaeva Z.; Ibragimova N. (1971)

3 β-Acetyl-α-3,4-epoxycarane under the influence of bases is easily rearranged to the α, β-unsaturated ketol, namely 3 β-acetyl-4-caren-3-ol, by the E2 mechanism of the β-elimination reaction. © 1972 Consultants Bureau.
Oxidation of 3-carene with oxygen in presence of chromig anhydride

Arbuzov B.; Isaeva Z.; Ibragimova N. (1962)

1. The oxidation of 3-carene with oxygtn in presence of CrO3 proceeds with predominant formation of ketones. 2. The primary products of the reaction are probably hydroperoxides, which decompose under the influence of the ...
Phosphoric esters containing a cyano group

Arbuzov B.; Zoroastrova V.; Ibragimova N. (1964)

1. Some mixed cyano-substituted phosphoric esters were synthesized by the reaction of dialkyl phosphorochloridates with acetone cyanohydrin. 2. By the reaction of diethyl phosphorochloridite with acetone cyanohydrin we ...
Preparation and structure of 2-acetyl-2,3-epoxycarane

Ibragimova N.; Vul'fson S.; Donskova A.; Bikeev S.; Vereshchagin A.; Samitov Y. (1982)

1. 2-Acetyl-α-2,3-epoxycarane which exists in solution as a single gauche conformer with minimal polarity was synthesized by the epoxidation of 2-acetyl-2-carene by perphthalic acid. 2. The conjugation in the system of ...
Stereochemistry of reduction of 4-acetyl-3α,4α-epoxycarane by sodium borohydride

Arbuzov B.; Vereshchagin A.; Isaeva Z.; Vul'fson S.; Ibragimova N.; Donskova A. (1979)

It was shown that the hydrogenolysis of 4-acetyl-3α,4α-epoxycarane using NaBH4 is accomplished stereoselectively in harmony with its steric structure. © 1979 Plenum Publishing Corporation.
Synthesis of esters of phosphonic acids, containing heterocyclic radicals - Communication 9. Reaction of benzylidenerhodanines with trialkyl phosphites and dialkylphosphorous acids

Arbuzov B.; Zoroastrova V.; Ibragimova N. (1967)

1. Trialkyl phosphites react with benzylidenerhodanine to give N-alkylbenzylidenerhodanines and dialkyl phosphites. 2. Dialkyl phosphites also alkylate benzylidenerhodanines and form addition products at the idene bond of ...
