The method as in 4-substituted-3,5-dimethyl-2,6-dioxo-piperidin acid compound as a raw material, is reacted with ammonia or an organic amine, in an organic solvent at 15 under the action of the enzyme at -60 ℃ Preparation of 4-substituted-2,6-dioxo-piperidine-3,5-dicarboxylic acid ...
In this case, the hydrolysis of the alkylated Schiff base is preceded by conversion of the carboxylic acid ester to an amide, e.g. by reaction with ammonia, mono- or dialkylamine to yield compounds of formula I, wherein R1 is carbamoyl, alkylcarbamoyl or dialkylcarbamoyl. Alternatively, ...
Carbamates are prepared from the substituted ethanol and phosgene followed by ammonia or an alkylamine, or a carbamic acid halide or ester or an isocyanate. Sulphoxides are prepared by oxidation with, for example, hydrogen peroxide. Examples are given. Alcohols of the formula: are prepared by...
The solvolyses by trifluoroethanoic (“trifluoroacetic” TFA) acid of several known and new thiocyanates have been studied using proton magnetic resonance. For the organic linkage isomers of RNCS (R = alkyl groups) isothiocyanates react (via N-alkyl monothiocarbamato trifluoroethanoates) to ...
a -Chloro-phenylacetamide is prepared from the acid chloride and ammonia.
METHOD FOR PRODUCING METHYLGLYCINE-N,N-DIETHANOIC ACID TRIALKALIMETAL SALTS WITH A LOW BY-PRODUCT CONTENTThe invention relates to a method for producing a light-coloured methylglycine-N,N-diethanoic acid trialkali metal salt with a low by-product content, by the alkaline hydrolysis of methyl...
(e) optionally the solution obtained in step (c) or (d) is reacted at a temperature ranging between 110 and 200 °C for a period of between 5 and 60 min; (f) hydrolysis and isolation of ammonia from the solution obtained in step (c), (d) or (e) by stripping at a temperature ...
The process is more ecologically friendly than previous processes in that large amts. of salts are not produced, and the very high excesses of the reactants ammonia and ortho methanoic acid esters previously necessary are avoided.METTLER, HANS PETER, DR.PREVIDOLI, FELIX, DR....
