Reaction of 3,4,6-tri-O-acetyl-2-deoxyglucopyranosyl bromide (1) with silylated 5-benzyluracil and subsequent ammonolysis afforded α- and β-anomers of 5-benzyl-1-(2-deoxy-D-glucopyranosyl)uracil (2 and 3). Under catalysis with tin tetrachloride, silylated 5-benzyluracil reacted with 1-O-acetyl-2,3,5-tri-O-benzoyl-D-ribofuranose to give 2',3',5'-tri-O-benzoyl-5-benzyluridine (10), which was converted into the 4-thio derivative 11 by reaction with Lawesson reagent.

Abstract:

Methyl and benzyl (ethyl 3,4-di-O-benzyl-2-O-benzoyl-1-thio-β-D-glucopyranosyl)uronate were synthesised from a protected thioglycoside in three steps. A regioselective ring opening of the benzylidene acetal with BH3.THF generated C6-OH material, which was subsequently oxidised using biphasic TEMPO/BAIB conditions. The resultant uronic acid was esterified with either a methyl or benzyl moiety. The products were obtained on a multigram scale and fully characterised by 1H, 13C and 2D NMR, alongside MS and IR analysis.

Abstract:

Ethyl 3,4,6-tri-O-benzyl-2-deoxy-2-phthalimido-1-thio-β-D-glucopyranoside (5), prepared by benzylation of ethyl 2-deoxy-2-phthalimido-1-thio-β-D-glucopyranoside (4), was transformed by reaction with bromine into 3,4,6-tri-O-benzyl-2-deoxy-2-phthalimido-β-D-glucopyranosyl bromide (6). Thioglycoside 5 in the presence of methyl triflate and glycosylbromide 6 in the presence of silver triflate were used as glycosyl donors for condensation with benzyl 2-acetamido-3-O-allyl-6-O-benzyl-2-deoxy-α-D-glucopyranoside (7), to give benzyl 2-acetamido-3-O-allyl-6-O-benzyl-4-O-(3,4,6-tri-O-benzyl-2-deoxy-2-p

Abstract:

Tetrahydroquinolines are important structural fragments of many biologically active compounds exhibiting antifungal, antitumor, antiviral and neurotropic properties. This paper presents methods for the synthesis of N-substituted tetrahydroquinoline-6-carbaldehydes and a study of the possibility of their olefination using the Wittig and Horner – Wadsworth – Emmons methods. As a result of the interaction of N-alkyl- and N-acylhydroquinolines with the Vilsmeier – Haack complex, N-substituted tetrahydroquinoline-6-carbaldehydes have been obtained in yields of 77–85%. Olefination of the obtained ca

Abstract:

Titanium(II) bis(tetrahydrofuran) 1, generated by the treatm ent of TiCl4 in THF with two equivalents of n-butyllithium at -78 °C, has been found to form carbon-carbon bonds with a variety of organic substrates by reductive coupling. Diphenylacetylene is dimerized to exclusively (E,E)-1,2,3,4-tetraphenyl-1,3-butadiene; benzyl bromide and 9-bromofluorene give their coupled products, bibenzyl and 9,9'-bifluorenyl, as do benzal chloride and benzotrichloride yield the 1,2-dichloro-1,2-diphenylethanes and 1,1,2,2-tetrachloro-1,2-diphenylethane, respectively.

Abstract:

A high-performance liquid chromatographic stability-indicating assaymethod in reverse-phase has been developed and validated for the simultaneous qualitative and quantitative measurement of triamcinolone acetonide and benzyl alcohol content in injectable suspension. The reverse-phase method was developed by using Inertsil ODS-2 column(100 x 4.6mm),5μm. with a mobile phase ratio comprised of water and acetonitrile mixed in 70:30 v/v ratio and pumped at a flow rate of 1.5 ml/min where the temperature of the column oven controlled at 40°C and sample compartment at 5°C with 10μL injection volume.

Abstract:

The kinetics of racemization of 2,4-disubstituted-5(4H)-oxazolones obtained from N-acetyl, N-benzoyl, and N-benzyloxycarbonylglycyl-L-leucine, -valine, and -phenylalanine have been studied in several solvents alone and in the presence of tertiary amines. The influence of the nature of the substituents on the rate of the reaction has been evaluated, and the values of the activation parameters ΔH≠ and ΔS≠ for the base-catalyzed reactions have been determined. The racemization process is governed by electronic effects of the C(2)-substituents and steric effects of the C(4)-substituents of the oxa

Abstract:

Among dermatological diseases demodicosis and acne occupy a very important place. The incidence of demodicosis is more than 5% and ranks seventh in frequency among dermatological diseases. It is known that demodicosis can turn into acne. Treatment of demodicosis and acne does not lose its relevance. This medical problem can be solved through the development of the composition and technology of a soft drug of complex action with the content of active substances used to treat these diseases. Since in dermatology for external use the optimal soft medicines is a cream (taking into account th
