Conclusions Some unsaturated diesters of the m- and p-carboranedicarboxylic acids, which can be used in polymerization and copolymerization reactions, were synthesized and characterized.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 8, p. 1904, August, 1982.     

Synthesis of unsaturated esters of pyridine- and quinolinedicarboxylic acids

The divinyl, diallyl, and dipropargyl esters of pyridine-2,4-, pyridine-2,6-, and quinoline-2,4-dicarboxylic acids and the divinyl and dipropargyl esters of pyridine-2,5-dicarboxylic acid have been synthesized.     

Reduction of quinolinecarboxylic acids by raney alloy

The heterocyclic nucleus in quinolinecarboxylic acids is reduced by Raney alloy (nickel-aluminium) in alkaline media to give 1,2,3,4-tetrahydro-2-,3-,4-,5-,6-, and 8-quinolinecarboxylic acids and 8-methyl-5-quinolinecarboxylic acid and their ethyl esters.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 1, pp. 77–79 January, 1988.     

The oxygen rearrangement of esters of aromatic and unsaturated acids

Conclusions The mass spectra of esters, thioesters, amides, and iminoesters of-phenylpropionic acid were studied.The basic principles directing the process of fragmentation of these compounds were determined. Translated fromIzvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 7, pp. 1552–1559, July, 1970.     

Method for synthesis of 1-adamantyl esters of unsaturated acids

New method for synthesis of adamantyl esters of acrylic, methacrylic, and cinnamic acids was developed. The reactions carried out under mild conditions in the absence of catalysts provide a high yield.     

Synthesis of esters of oxocaprylic acids

Conclusions On hydrogenation over Pt-C in the vapor phase (240–250°), esters of -(5-methylfuryl)-propionic acids undergo hydrogenolysis of the C-O bond in the furan ring and are converted into the corresponding esters of-oxocaprylic acid (35–50%) and-oxocaprylic acid (25–35%).Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 2, pp. 420–422, February, 1967.     

Synthesis of esters of allenic acids

Conclusions Starting with 1,1-dimethoxy-1-buten-3-yne, a method was proposed for the synthesis of the esters of -hydroxyallenic acids and of a 5-dialkylamino-2,3-pentadienoic acid.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 9, pp. 2089–2090, September, 1971.     

Synthesis and transformations of unsaturated carboxylic acids

Summary A new method was developed for synthesizing diene -keto acids and their esters based on available furylacetylenic -glycols.For Communication 1 of this series see Izv. AN SSSR, Otd. Khim. Nauk, 1512 (1960).     

Synthesis of choline esters of carboranecarboxylic acids

Conclusions The choline esters of a number of o- and m-carborane mono- and dicarobxylic acids were synthesized by reacting the corresponding acid chlorides with dimethylaminoethanol in the presence of triethylamine.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 11, pp. 2606–2608, November, 1976.     

Synthesis of inulin esters of phenylcarboxylic acids

Inulin esters were synthesized containing residues of ferulic, p-hydroxycinnamic, and vanillic acids with a maximum degree of substitution of 1.1. The inulin acylation was carried out with chlorides of 4-acetoxy derivatives of the corresponding hydroxyphenylcarboxylic acids in a heterogenic water-organic environment. The removal of the protecting acetyl group at the phenol hydroxyl was carried out by treating with pyrrolidine or ammonium acetate. The solubility of the esters obtained was evaluated.     

Synthesis of aminooxyphosphonic acids and their esters

Conclusions The Arbuzov reaction and alkylation by -haloalkylphosphonic esters gave diesters of aminooxymethane-, -aminooxyethane-, and -aminooxybutanephosphonic acids; aminooxymethane- and -aminooxyethanephosphonic acids; and monoesters of -aminooxyethanephosphonic acid.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 5, pp. 1202–1204, May, 1986.
