Übersetzung für "Derivatizing" in Deutsch

With other words, the method according to the invention is a method for derivatizing an amino group.

Another viable derivatizing of the carboxy function lies in a conversion to amide.

The derivatizing of the silanized surfaces was also performed by use of 2,3,5,6-tetrabromo- or 2,3,5,6-tetrafluoro-or 2,3,5,6-tetraiodo-cyclohexadiene-1,4-dione.

Derivatizing the porous silicate material was also performed with use of 2,3,5,6-tetrabromocyclohexadiene-1,4-dione, 2,3,5,6-tetraiodocyclohexadiene-1,4-dione.

The derivatizing of the silanized surfaces was also performed with the use of 3,4,5,6-tetrabromocyclohexadiene-1,2-dione or 3,4,5,6-tetrafluorocyclohexadiene-1,2-dione.

Derivatizing the cysteine with ninhydrin in strongly acid conditions removes it from the equilibrium.

It has now been found that by the substitution of the 5-hydroxymethyl group by an oxygen atom and by other derivatizing of the function groups, LTB4 analogs are obtained which greatly antagonize the action of the natural LTB4.

Decomposition-sensitive complex ligands can be stabilized by derivatizing them with the aid of bulky secondary or tertiary carboxylic acids or sulfonic acids.

The further derivatizing takes place by oximation or thioketalization in the 3 position and with the presence of a 20 hydroxy group optionally by its acylation, aroylation or oxidation, and other compounds of general formula I according to the invention are used.

Compounds of formula I in which Ind is an indol-3-yl radical substituted by CO--R1 can be obtained by derivatizing appropriate carboxyindol-3-yl compounds.

The organic compounds (b) can be prepared by the known methods of organic chemistry for the synthesis of esters, ethers and carbonates by starting from sulfonium salts having phenolic groups and derivatizing them appropriately.

The compounds (c) can be prepared by the known methods of organic chemistry for the synthesis of esters, ethers and carbonates by starting from aromatics having phenolic groups and derivatizing them appropriately.

It has now been found that by the substitution of the 5-hydroxy group by a hydrogen atom and by other derivatizing of the functional groups, LTB4 analogs are obtained which greatly antagonize the action of the natural LTB4.

For some applications, it is advantageous if the collector surface is capable of selective chemosorption or of derivatizing defined components by providing it with special coatings.

Derivatizing, for example the preparation of trimethylsilyl derivatives, can be carried out readily in the presence of a collector surface with nonpolarized coating or covering which, due to its low polarity, will preferably adsorb the derivative when the reaction mixture is cooled.

The organic compounds (b) can be prepared by the methods known in organic chemistry for the synthesis of esters, ethers and carbonates by starting from the sulfonium salts with phenolic groups and derivatizing them appropriately.

A process for the preparation of the compound characterized under 1., which comprises derivatizing the OH group located in the 3' and/or 2' position of the nucleoside, nucleotide or oligonucleotide to an amino or thiol group, and subsequently coupling on a fluorescent dye.

The most promising methods include the spinning of solutions of the cellulose in amino oxides, preferably in N-methyl morpholine N-oxide (NMMNO), particularly because the cumbersome path via a derivatizing of the cellulose is avoided.

As described above, the step of introducing a protecting group or derivatizing the hydroxyl (R5) can also be carried out simultaneously or subsequently to the process according to the invention.

Such isocyanates are obtained, for example, by reacting difunctional isocyanates with one another and derivatizing some of their isocyanate groups to give allophanate or isocyanurate groups.

The carboxylic acids I.2 are activated and derivatized, for example, by converting into acid chlorides by means of thionyl chloride, oxalyl chloride or phosgene and subsequently derivatizing by nucleophilic replacement of the chlorine atom, by activating by means of e.g. N,N'-dicyclohexylcarbodiimide (J. Am.

Prepolymers (components A) which are likewise suitable are unsaturated polyester prepolymers or polyester resins, and also the ethylenically modified polyesters that are synthesized by derivatizing the free OH groups in conventional polyesters with a,?-ethylenically unsaturated structural units such as vinyl- or allyl-functional hydroxyalkanes, vinyl or allyl esters of aliphatic, functionalized carboxylic acids, and esters of a,?-ethylenically unsaturated carboxylic acids with diols and polyols, and also the so-called ethylenically unsaturated polyesters that are obtainable by copolycondensation of conventional dicarboxylic acids together with ethylenically unsaturated dicarboxylic acids and/or their anhydrides and low molecular mass diols.

A distinction should be made here between, on the one hand, materials termed ethylenically unsaturated polyesters which are obtainable by copolycondensation of conventional dicarboxylic acids together with ethylenically unsaturated dicarboxylic acids and/or with anhydrides of these and with low-molecular-weight diols, and on the other hand ethylenically modified polyesters obtainable by derivatizing free OH groups in conventional polyesters.

If individual compounds I cannot be obtained by the above-described routes, they can be prepared by derivatizing the compounds I.

Surprisingly, it has now been found that these substances can be stabilized by derivatizing them by means of bulky secondary or tertiary carboxylic acids or sulfonic acids.

Compounds of the formula I in which Ind is an indol- 3-yl radical substituted by CO-R1 can be obtained by derivatizing appropriate carboxyindol-3-yl compounds.
