    摘要: Nanostructures are formed from alkylated derivatives of aromatic acids of the formula:

    wherein at least one of R 1 to R 6 represents a carboxylic acid group, a primary amide group, an ester group, an amidine group, or a salt thereof, at least one other of R 1 to R 6 is X-R c , and the remaining of R 1 to R 6 independently represent H or substituted or unsubstituted organic groups; X represents a linking group; and R c represents a substituted or unsubstituted alkyl group.

    摘要: A method for preparing a phenylalanine derivative having a quinazoline-dione ring represented by the following formula (1) or a pharmaceutically acceptable salt thereof, comprising the following steps (a), (b) and (c):

    (a) reacting an acyl phenylalanine derivative represented by the following formula (2):

    with a carbonyl group-introducing reagent and a specific anthranilic acid derivative to thus form the corresponding carboxy-asymmetric urea derivative;
    (b) converting the carboxy-asymmetric urea derivative into the corresponding quinazoline-dione derivative in the presence of a carboxyl group-activating agent:
    (c) if desired, substituting an N-alkyl group for the hydrogen atom bonded to the nitrogen atom present in the quinazoline-dione ring of the quinazoline-dione derivative using an N-alkylation agent and then deprotecting the resulting product, when the substituent R3' which is a group corresponding to R3 is protected. According to this method, there can be obtained a phenylalanine derivative having a quinazoline-dione skeleton in a industrially favorably high yield.
