Synthetic procedure to access the first representatives of a new series of 3-monosubstitued functional derivatives of 1-alkoxy-1-triazene 2-oxides, i.e., 1-alkoxy-3-(2-hydroxyethyl)- and 1-alkoxy-3-(2-acetoxyethyl)-1-triazene 2-oxides, were elaborated. 1-Alkoxy-3,3-bis(2-hydroxyethyl)-1-triazene 2-oxides were used to derive 3-(2-acetoxyethyl)-, 3-(2-bromoethyl)- and 3-(2-cyanoethyl)substituted 1-alkoxy-3-(2-acetoxyethyl)-1-triazene 2-oxides. 相似文献

The possibility of synthesis of 3-(β-hydroxyethyl)-1,3-oxazolidin and its substituted derivatives at position 2 by the condensation-heterocyclization of diethanolamine with certain aldehydes and ketones was examined. The structure of
the compounds was identifi ed by NMR spectroscopy. We investigated antimicrobial properties of the synthesized compounds against
microorganisms that affect the lube oil M-11 and found a dependence of the antimicrobial properties on the nature of the substituent
at position 2 of oxazolidin heterocycle. 相似文献

2,2-Dialkyl(phenyl)-4-(2-hydroxyethyl)thiadiazin-5-ones are formed as a result of the reaction of thioglycolic acid with 2-hydroxyethylhydrazones. The structures of the reaction products were proved by PMR and 13C NMR spectrometry and the mass spectra.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 6, pp. 838–839, June, 1991. 相似文献

The title azaazulene 3 was synthesized either by reaction of tropone with N-{(2-pyridyl)acetyl}pyridinium iodide in the presence of ammonium acetate or by palladium-catalyzed cross-coupling between 2-halo-1-azaazulene and 2-substituted pyridine. The compound shows relatively stronger basicity compared with 2,2′-bipyridyl. While 3 showed no emission from the S1 state but from the S2 state like azulene does, the protonated species of 3 exhibited emission from the S1 state. Cationic metal-dependent absorption and emission relating to complexation were also studied. 相似文献

Three diaastereomers of 4 - (1,1 -dimethyl - 2 - propenyl) - 3 - hydroxyethyl - 2 -azetidinones 2, 3, and 11 were obtained by the reaction of acetaldehyde with the enolate of the silyl azetidinone 5 and dilithiated intermediate 10: The trans isomers 2 and 3 were converted into 6 - (1 - hydroxyethyl) - 1,1 - dimethyl - 1 - carba - 2 - penems 19 and 20via a Dieckmann-type cyclization. 相似文献

Substituted ]-(6-methoxy-2-benzothiazolyt)-2-pyridones were prepared from 2-amino-6-methoxybenzathiazate through N-(6-methoxy-2-benzothiazotyl) cyanvorearmileaznd-3-aryl-N-(6-methoxy-2-benzothiazolyt)-2-cyano-2-propenamides. The cyclization of the latter with malonodinitrile in the presence of piperidine gave the corresponding pyridones. The structures of the synthesized compounds were confirmed by1H NMR and mass spectral data.Department of Organic Chemistry, Mass Spectrometry Laboratory, Slovak Technical University, 812 37 Bratislava, Slovakia.

The conjugates of cyclic glycerolphospholipids and N1-(2-furanidyl)-N3-(2-hydroxyethyl)-5-fluorouracil have been synthesized by a one-pot procedure. The hexaethylphosphorus triamide activated by a catalytic amount of iodine was used as the phosphorylating and cyclizing reagent. © 1998 John Wiley & Sons, Inc. Heteroatom Chem 9:295–298, 1998 相似文献
