Abstract: The invention comprises Ne -palmitoyl-L-lysine and Ng - palmitoyl - (L - a ,g - diamino-butyric) acid and their alkyl esters containing up to six carbon atoms in the alkyl residue characterizing the ester group. The acids are prepared by heating L-lysine hydrochloride a L-a ,g -diamino-butyric acid hydrochloride with basic copper carbonate, acylating the resulting complex under alkaline conditions with palmitoyl chloride, acidifying the acylation product, removing the copper by precipitation with hydrogen sulphide and rendering the mixture neutral to precipitate the product. The acids are esterified by reaction with an alcohol and hydrogen chloride or thionyl chloride.

Abstract: 1310656 Peptide process F HOFFMANNLA ROCHE & CO AG 24 Sept 1971 [26 Sept 1970] 44701/71 Heading C2C [Also in Division C3] In a peptide process an amino acid which is linked via an ester or amide bond to a polymer which is soluble in water and/or an organic solvent is stepwise coupled in a homogeneous phase with further amino acids and the polymer removed from the peptide. Polymers have mol. wts. of up to 100,000 and are preferably polyethylene glycol optionally esterified with citric acid or a copolymerizate of vinyl pyrrolidone and acrylic acid #-hydroxyethylacrylate or of acrylamide and vinyl acetate in which the ester groups are partially saponified at least, or a copolymerizate of polyethylene glycol and succinic acid. In the process lower molecular coupling reagents are removed by dialysis, membrane filtration, column chromatography or countercurrent distribution and the polymer is removed from the peptide by treatment with dilute alkali hydroxide. Maleic acid di-(p-nitrophenyl) ester is prepared from the acid and phenol in the presence of dicyclohexylcarbodiimide and then with HI to give mono iodo succinic acid di-(p-nitrophenyl) ester.
