    摘要: The present invention is directed to a composition and method relating to the preparation of aspartyl peptides having the general formula: ##STR1## where the radical-NHR represents an amino acid or peptide group. In the method, a .beta.-monoester of aspartic acid having the general formula: ##STR2## where R.sub.1 represents a hydrocarbon-containing radical, is reacted with a .beta.-dicarbonyl compound, preferably ethylacetoacetate to protect the aspartyl amino group and form an enamine. The enamine is then coupld to an amino acid or peptide, following which any protecting groups are removed to yield .alpha.-aspartyl peptides without any .beta.-isomer. In its composition aspects, the present invention is directed to novel enamines resulting from reaction of the .beta.-monoester of aspartic acid with a .beta.-dicarbonyl compound.

    摘要: The reaction of an imidazoline base of the formula: ##STR1## wherein R represents an aliphatic group comprising from 6 to 22 carbon atoms and R.sub.1 represents a substituted or unsubstituted alkyl or alkenyl group comprising 1 to 4 carbon atoms, with a carbo-alkylating agent is carried out in two stages. Initially the pH is maintained in the range 7 to 11 and subsequently it is maintained in the range 9 to 12.5. These conditions encourage at least part of the imidazoline to undergo alkylation followed by hydrolysis and further alkylation. The di alkylated amidoamines thus produced are believed to be novel. The reaction products are surfactants which exhibit very low skin irritancy and have a desirably low viscosity. They find particular application in shampoo formulations.

    摘要: N-mono-substituted derivatives of diamino acids are prepared by the reaction of succinimidyl esters of carboxylic acids or substituted carbonic acids with the unprotected diamino acid. The acylation preferentially occurs at the side chain or terminal amino group of the diamino acid. For example, selective acylation of the terminal amino group of lysine occurs without first having protected the 2-amino group. Such acylation has application in the preparation of inter alia N.sup.6 -palmitoyl-lysine.
