Chemistry of heterocyclic N-oxides and related compounds

The dehydrogenating activity of 4-nitropyridine N-oxide and picolinic, nicotinic, isonicotinic, and quinolinic acid N-oxides was studied in the case of the reaction with the Hantzsch ester.See [1] for communication VIII.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 12, pp. 1651–1653, December, 1977.     

Chemistry of heterocyclic N-oxides and related compounds. 11. Reaction of pyridine N-oxide with metal ketyls and benzophenone dianions

The reaction of pyridine N-oxide with metal ketyls of benzophenone was studied. It is shown that diphenyl(2-pyridyl)carbinol N-oxide is formed with the lithium and sodium derivatives of benzophenone, whereas diphenyl(2-pyridyl)carbinol is formed with the potassium derivative of benzophenone. Diphenyl(2-pyridyl)carbinol N-oxide is obtained in lower yields in the reaction of pyridine N-oxide with benzophenone dianions. Pyridine and 4,4- and 2,2-dipyridyls are simultaneously formed in all of the reactions.See [1] for Communication 10.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 5, pp. 655–658, May, 1979.     

Reaction of α-chloro-β-oxobutanal with indole derivatives

The reactions of 2-methylindole and 2-methylindol-3-yldiphenylphosphine with α-chloro-β-oxobutanal was studied.     

Investigation of Chemical Properties and Antimicrobial Activity of Acetylene Glycidyl Ethers

Reactions of acetylene glycidyl ethers with butylamine and ethylene diamine lead to the oxirane ring opening according to the Krasusky rule with the formation of acetylene aminoalcohols. In reaction with thiourea the oxygen atom in the ring is replaced by sulfur leading to the corresponding thiiranes in a high yield. The synthesized compounds possess high antimicrobial activity.
