ORGANIC-SYNTHESISSILAFUNCTIONAL COMPOUNDSCONJUGATE ADDITIONO(3-Oxo-3-phenyl)propylvinylsilanes, new functionalized monomers, have been synthesized in modest to good yields, by the reaction of methyl benzoates with chlorodimethylvinylsilane in the presence of magnesium. The synthetic potential of these ...
The thermal reaction of methyl 2-oxo-2H-pyran-5-carboxylates with substituted styrenes in the presence of 10% palladium on activated carbon afforded directly the corresponding methyl 4-biphenylcarboxylates in good yields. By the similar procedure, methyl 4-heteroaryl- and 4-alkyl-substituted benzo...

investigated by using single-factor experimental method.The optimum conditions was found as follows: 1.64%catalyst based on benzoic acid,molar ratio of benzoic acid to n-butyl alcohol 1:2.0,and reaction time was 3.5 h.Under the optimum conditions,the esterification of n-butyl benzoate was about ...
Synthesis and pharmacological activity of ω-aminoacyl esters of the stereoisomeric tropan-3-ols It is more convenient, however, to carry out the reaction of the hydrochloride with one mole of secondary amine in alcohol to give the dihydrochloride of the aminoester directly. The secondary amines ...
Methyl benzoate functionalized phenylenediamine derivatives with the methoxycarbonyl groups at the ortho metaand para﹑ositions of amino group were synthesized via palladiumヽatalyzed Buchwald〩artwig reaction and copperヽatalyzed Ullmann amination. Crystallographic analysis unraveled the presences of intraand...
Synthesis of primary amides andN-Me secondary amides In our synthetic method, NaAB is soluble and stable in organic solvents62. Its reaction with methyl benzoate is selected as a model reaction to examine the reaction conditions and characterize the products. The reactions were carried out at room...
in the presence of zinc chloride in ether or in the presence of aluminium chloride in benzene; the reaction takes place readily, however, in the presence of anhydrous aluminium chloride dissolved in dry ether, with the formation of the aldehyde ester, methyl 2: 4 dihydroxy-3-formyl benzoate....
2.1.1. General procedure for the synthesis of p-methyl benzoyl thiosemicarbazide: 1 A mixture of ethyl-p-methylbenzoate(0.01mol) andthiosemicarbazide(0.01mol) in methanol (25 ml) was refluxed for 10 h. The solvent was removed under reduced pressure and the viscous mass poured over ice water,...
