Unexpectedly easy non-catalytic transfer of allyl group from allyl sulfides to secondary phosphine sulfides

Chernysheva N., Verkhoturova S., Nalibayeva A., Bishimbayeva G., Arbuzova S., Zinchenko S., Trofimov B.

摘要

The unexpected allylation of secondary phosphine sulfides with allyl sulfides has been found. The reaction proceeds under mild conditions (no catalyst and solvent, 80°C) to give allyldiorganylphosphine sulfides (yield up to 79%). The latter, under the reaction conditions, are able to add the initial secondary phosphine sulfides across the allyl group in the anti-Markovnikov mode to deliver propane-1,3-diylbis(diorganylphosphine sulfides), promising extractants of heavy metals and ligands for the synthesis of metal complex catalysts.

Catalyst-free reactions of Schiff bases with cyanopropargyl alcohols: synthesis of functionalized 1,3-oxazolidines

Oparina L., Grishchenko L., Kolyvanov N., Ushakov I., Trofimov B.

摘要

Schiff bases react with cyanopropargylic alcohols (80°C, 10-12 h) in the absence of catalysts and solvents to afford functionalized 1,3-oxazolidines in up to 82% yield. The reaction proceeds through a cascade of transformations including the formation of a 1,3-dipolar intermediate via the addition of a neutral N -nucleophile to the activated triple bond, the proton transfer from the hydroxyl group to the carbanionic center of the intermediate, and the intramolecular attack of the carbonyl carbon of the Schiff base by the O -centered anion to close 1,3-oxazolidine cycle.

Synthesis of 1-(adamantan-1-yl)propan-1,2-diamine and chiral ligands based thereon

Mankova P., Reznikov A., Shiryaev V., Tkachenko I., Klimochkin Y.

摘要

Racemic 1-(adamantan-1-yl)propan-1,2-diamine which was resolved with l-malic acid was obtained from trans-2-(adamantan-1-yl)-3-methylaziridine. The isolated (1 S ,2 R )-isomer was derivatized with benzyl. Enantiomeric excess of (2 S ,3 R )-2-(adamantan-1-yl)-3-methyl-5,6-diphenyl-2,3-dihydropyrazine was determined by HPLC. (4 S ,5 R )-4-(Adamantan-1-yl)-5-methylimidazolidine-2-thione was synthesized by the reaction of (1 S ,2 R )-diamine with carbon disulfide; absolute configuration was determined by X-ray diffraction analysis. Ligands were synthesized on the basis of racemic and chiral (1 S ,2 R )-1-(adamantan-1-yl)propan-1,2-diamines. The catalytic activity complexes were studied using Michael, Henri and epoxidation model reactions. For the model reaction of Henri stereodivergence was noted when using ligands of a similar structure.

Synthesis of 5,7-dichloro-2-adamantanone

Skomorokhov M., Zaborskaya M., Ivleva E., Shiryaev A., Klimochkin Y.

摘要

The reaction of 2-adamantanecarboxylic acid with an excess of chlorine in the presence of AlCl3 under heating gave 5,7-dichloro-2-adamantanecarboxylic acid. This product was sequentially introduced into the Curtius, deamination, and oxidation reactions to form 5,7-dichloro-2-adamantanone. The resulting product is a key substrate for synthesis of new substances and materials with a set of practically important properties, including both the synthesis of biologically active molecules and systems for chemiluminescent diagnostic methods.

Reactions of 1,3-dihaloadamantanes with nitric acid

Ivleva E., Simatova E., Klepikov V., Khatmullina Y., Klimochkin Y.

摘要

The reaction of 1,3-dibromoadamantanes with fuming nitric acid gave the mixture of 2-oxaadamantane derivatives. In the same conditions 1,3-diiodoadamantanes gave the corresponding 1,3-dinitroxyadamantanes. A preparative method for the synthesis of 5,7-dimethyl-3-bromomethyl-1-hydroxy-2-oxaadamantan-1-ol from 5,7-dimethyl-1,3-dibromoadamantane was developed. The obtained compounds can be used in the directed synthesis of substances with high molecular complexity for studying of biological activity.

Chemical transformations of 3-bromoethyl-5,7-dimethyl2-oxaadamantan-1-ol in sulfuric acid

Ivleva E., Simatova E., Zaborskaya M., Kazachkova M., Rybakov V., Klimochkin Y.

摘要

The reactions of 3-bromomethyl-5,7-dimethyl-2-oxaadamantan-1-ol in a 96% acid medium both in the presence and in the absence of nucleophiles were studied. During the reactions a number of structural transformations of the 2-oxaadamantane cage take place. The possibility of obtaining 1,2,3-trisubstituted adamantanes is also presented. The structural features of new compounds are investigated using 2D NMR spectroscopy and XRD analysis. The obtained compounds can be used in the directed synthesis of a new cage heterocycles for studying of biological activity.

Reactions of β-nitro-substituted 1H-benzo[f]chromenes and benzofurans with nucleophiles

Osipov D., Artyomenko A., Korzhenko K., Raschepkina D., Demidov O., Osyanin V.

摘要

A series of 3-alkoxy-2-nitro-2,3-dihydro-1 H -benzo[ f ]chromenes as a mixture of cis - and trans -isomers was obtained in the reaction of 2-nitro-1 H -benzo[ f ]chromenes with alcohols. The reaction with secondary cyclic amines and 3-amino-5,5-dimethylcyclohex-2-en-1-one proceeds trans -diastereoselectively to form Michael adducts of benzochromane structure. Conjugated addition involving anilines leads to (2-hydroxy-1-naphthyl) methyl-substituted β-nitroenamines. The nucleophilic dearomatization of 3-nitrobenzofurans under the action of primary aromatic amines was shown to involve sequential aza- and retro-oxa-Michael reactions. This reaction illustrates the high propensity of 3-nitrobenzofurans to open the furan cycle.
