According to the present invention, a process is provided for producing an acyl group-containing composition that includes a step of reacting a long chain N-acyl acidic amino acid anhydride with one or more compounds which have, per molecule, m functional groups of one kind or more selected from the group consisting of hydroxyl, amino and thiol groups in an aqueous solvent and/or a mixed solvent of water and an organic solvent (reaction step). The process makes it possible to produce an acyl group-containing composition that is free from coloration under moderate conditions.
摘要:
.omega.,.omega.-Dialkoxycarboxylic acid derivatives I (amides and esters) are prepared by heating .omega.-alkoxylactams II with hydrogen halide in an alcohol. When using only a catalytical quantity of hydrogen halide, there are obtained the amides, when using a quantity of hydrogen halide which is at least about equimolar, there are obtained the esters of the corresponding .omega.,.omega.-dialkoxycarboxylic acids. Since the compounds I are acetals, they may be readily converted into the corresponding .omega.-formyl compounds. Both the acetals I and the corresponding .omega.-formyl compounds are valuable intermediates for the synthesis of for example prostaglandins, sexual attractants and antioxidants.
摘要:
Process for preparing di-n-propyl acetamide of the formula: ##STR1## whereby di-n-propyl acetonitrile is hydrolyzed by means of 80% sulphuric acid aqueous solution in the proportion of 2 to 2.5 g of dilute acid/g of nitrile, at a temperature between 80.degree. C and 130.degree. C to obtain the desired amide.

摘要:
Derivatives of 2-hydroxy-3,3,3-trifluoro-2-(alkyl or trifluoromethyl)propionic acid bearing a phenyl or naphthyl group linked to the 2-hydroxy group either directly or via an intermediate methylene group. The compounds reduce the concentrations of cholesterol, total esterified fatty acids or fibrinogen in the blood plasma of test animals and some compounds show anti-arthritic properties.
