    摘要: 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.
