The stereospecificity of epoxidation and the chemoselectivity of oxidation of hydroxy groups in the reactions of 20,29-lupene triterpenoids with dimethyldioxirane is discovered.
The X-ray diffraction studies and B3LYP/6-311G * calculations of the complexes of 1-boraadamantane and 4-bromo-1-boraadamantane with THF have revealed that the introduction of a halogen atom results in a shortening of the B −O bond due to intramolecular polarization.
Secondary phosphine sulfides react chemo- and regiospecifically with alkyl vinyl ethers under radical conditions in the anti-Markovnikov mode giving corresponding tertiary phosphine sulfides in high yield.
The reaction of N -benzoyl-2-(cyclohex-2-en-1-yl)aniline 1 with molecular oxygen in the presence of NaHCO 3 results in N -benzoyl-1-iodo-1,2,3,4,4a,9a-hexahydrocarbazole, which was isomerised to 1-phenyl-2a,3,4,5,5a,10a-hexahydro(1,3)oxazolo-(5,4,3- j,k )carbazol-10-ium iodide, whereas the...
The use of the ionic liquid (bmim)Cl·2AlCl 3 for the preparation of dihydropyrimidinones is described.
The influence of Cu 2+ ions on the state of mixed phosphorylated methanofullerene–lecithin monolayers and vesicles has been estimated.
Temperature-dependent measurements according to the modified Eyring equation allowed the evaluation of the displacement selectivity of the nitro group and fluorine in the S N Ar reactions of 3-nitro-5-R-benzotrifluorides (R = NO 2 , F) with the nucleophiles (2ArYH)·K 2 CO 3 and ArY−K + (Y = O,...
A method for the synthesis of previously unknown 2-aryl-4,6-dinitrobenzo( d )isothiazolium has been developed based on the replacement of ortho -NO 2 in N -(2,4,6-trinitrobenzylidene)anilines by treatment with PhCH 2 SH/K 2 CO 3 followed by conversion of the resulting N...
Acyloxy group exchange at the nitrogen atom proceeds in the interaction of N -acyloxy- N -alkoxyureas, N -acyloxy- N -alkoxybenzamides and N -acyloxy- N -alkoxycarbamates with Na and K carboxylates in MeCN.
The reaction of 2-acetyl-5-methyl-2 H -1,2,3-diazaphosphole with ( rac )-butane-2,3-diol at temperatures below 0 °C leads to the formation of a hydrospirophosphorane containing both a diazaphospholene and a dioxaphospholane ring system and a β-hydroxyalkoxy-1,2,3-diazaphospholene. On heating,...
