The pseudo-four component click synthesis of dibenzylated 1,2,3-triazoles derived from aniline is reported. The cycloaddition of sodium azide to N-(prop-2-ynyl)-benzenamine (I) in the presence of equimolar amounts of p-substituted benzyl derivatives, yields a mixture of mono- and dibenzylated 1,2,3-triazoles. When two equivalents of the benzyl derivative are added to the multicomponent reaction...

In the crystal structure of the title compound, [ReCl(C(26)H(22)NP)(CO)(3)]·CH(2)Cl(2), the Re(I) atom exhibits a distorted octa-hedral environment defined by a facial arrangement of three carbonyl groups, a Cl atom and an N-[2-(diphenyl-phosphino)benzyl-idene]benzyl-amine ligand. The compound crystallizes with one CH(2)Cl(2) mol-ecule per asymmetric unit. The benzyl-amine ligand and the Re(I) ...

The specificity of substrates for measuring cystyl-amino peptidase activity in pregnant serum in the assessment of placental function was studied, using £-cystine-di-j3-naphthylamide, L-cystine-bis-/?-nitroanilide,/,-cysteine-j3naphthylamide, and S-benzyl-i-cysteine-p-nitroanilide. The enzyme activity with S-benzyl-Z,-cysteine-/?-nitroanilide increased more rapidly and markedly than with other ...

The synthesis of (2S)-2-benzyloxymethyl-3-(2-fluoro-4-methoxyphenyl)- propionic acid, (2S)-2-benzyloxymethyl-3-(2-fluoro-4-methylphenyl)propionic acid and (2S)-2-benzyl-oxymethyl-3-(2,4-dimethylphenyl)propionic acid has been achieved by TiCl4 mediated alkylation of the corresponding (4R)-4-benzyl-3-[3-(2-fluoro-4-methoxyphenyl-, 2-fluoro-4-methylphenyl-, 2,4- dimethylphenyl-)propionyl]-2-oxazol...

In the solvent free oxidation of benzyl alcohol, using supported gold-palladium nanoalloys, toluene is often one of major by-products and it is formed by the disproportionation of benzyl alcohol. Gold-palladium catalysts on acidic supports promote both the disproportionation of benzyl alcohol and oxidative dehydrogenation to form benzaldehyde. Basic supports completely switch off disproportiona...

In the title compound, C30H33BrO6, the pyran-ose ring adopts a chair conformation. Two of the O-benzyl phenyl rings lie almost perpendicular to C/C/C/O plane formed by the ring atoms not attached to these O-benzyl phenyl rings, and form dihedral angles of 85.1 (2) and 64.6 (2)°, while the third O-benzyl phenyl ring is twisted so that it makes a dihedral angle 34.9 (2)° to this C/C/C/O plane. Th...

field trials with dizigotheeca elegantissima were conducted at the experimental farm of faculty of agriculture, azad university  jiroft  in growth seasons of 2012 year. the aim of this work was to study the effect of foliar application of gibberellic acid [ga3] and benzyladenine [ba] at 0, 50, 100 and 150 mgl-1 on the vegetative growth and photosynthetic pigments of d. elegantissima plants. mos...

Novel 3-(3-benzyl-2,3-dihydrobenzo[ d]thiazol-2-yl)benzo[ d]oxazole-2(3 H)-thione derivatives are efficiently synthesized in excellent yields by reactions of benzothiazoles, benzyl bromides, and 2-mercaptobenzoxazole acetone under catalyst-free conditions the presence triethylamine. The structures products confirmed nuclear magnetic resonance spectroscopy, infrared electron ionization mass spec...

A new strategy has been developed for the benzylation of nitriles directly from benzyl alcohols. In this process benzyl alcohols undergo retro-Claisen activation with cyanoacetic esters to generate an active electrophile and a carbanionic nucleophile. In the presence of Pd(0) these intermediates undergo catalytic coupling to generate a new C-C bond, resulting in the formation of phenyl propioni...

The copper-catalyzed tandem oxidative cyclization of cinnamamides with benzyl hydrocarbons through the direct cross-dehydrogenative coupling of sp(3) and sp(2) C-H bonds has been developed. Satisfactorily, ethers, alcohols and alkanes could also be used instead of benzyl hydrocarbons in this transformation, which allows rapid access to diverse dihydroquinolinones in one step.
