SYNTHESIS OF 3-ARYLMETHYL-4- THIAZOLIDINE-CARBOXYLIC ACID-2-ONES AND 2-THIONES
Barium salts of dibenzylidene cystines 8a-c were obtained from the reaction of Lcystine with benzaldehyde or its derivatives in the presence of barium hydroxide. Their reduction with zinc and hydrochloric acid in methanol yielded the Narylmethylcysteines ?9a-c?. These can, in turn, be converted by esterification into the methyl esters ?10 a-c. ?Reaction of N, N'-carbonyl diimidazole (Im C...
متن کاملSynthesis of Deuterium - labeled 1 - Aminocyclopropane - 1 - carboxylic Acid
[ ZH2 IACC) ; 1-amino [ 2R, 3E-2H2] cyc lopropaneIcar boxy 1 ic acid (trans-[zH2]ACC) : and l-amino[2,2.3.3-~H~]cyclopropane1-carboxylic acid are described. The [2,2-2H2]and [2,2,3.3-2H4]ACC compounds were prepared from the appropriately deuterated 2-bromoethanol 4-methylbenzenesulfonates by reaction with ethyl isocyanoacetate and two moles oE sodium hydride. The transr2H2]ACC and &[2H2]ACC wer...
متن کاملsynthesis of 2-phosphonobutane-1, 2, 4-tricarboxylic acid
2-phosphonobutane-1,2,4-tricarboxylic acid is(pbtc) a member of phosphonate family, and used as corrosion and scale inhibitor in cooling water systems. phosphonocarboxylates as a member of organophosphorus compounds have c-p and p-o bonds in their structures. pbtc is mainly used as carbonate scale inhibitor (caco3), sulphate scale inhibitor (caso4), corrosion inhibitor of low alloyed steel, eff...
متن کاملSynthesis and structural characterization of 1- and 2-substituted indazoles: ester and carboxylic acid derivatives.
A series of indazoles substituted at the N-1 and N-2 positions with ester-containing side chains -(CH2)(n)CO2R of different lengths (n = 0-6, 9, 10) are described. Nucleophilic substitution reactions on halo esters (X(CH2)(n)CO2R) by 1H-indazole inalkaline solution lead to mixtures of N-1 and N-2 isomers, in which the N-1 isomer predominates. Basic hydrolysis of the ester derivatives allowed th...
