    摘要: The invention concerns a method of producing oxazolidinones of formula (I), wherein R1-R5 have the meanings given in the description, by reacting cyclical anhydrides of formula (II) with carbonyl compounds of general formula (III) at temperatures between ambient temperature and approximately 150° C. The invention also concerns the production of the cyclical anhydrides of formula (II) by reacting N-protected aminodicarboxylic acids of formula (IV) with a dehydrating agent in situ. The invention further concerns the use of oxazolidinones of formula (I) for the &agr;-selective production of esters of formula (V) and amides of general formula (VII).

    摘要: The present invention is concerned with the formation of amide bonds. More specifically, the present invention, relates to processes for the manufacture of organogellant compounds (OG) as depicted below wherein L is selected from C2-C20 alkyl, C6-C20 aryl, C7-C20 alkylaryl, R1 are side chain substituents and one of X1, X2 is nitrogen and the other two are carbon. Processes of the present invention employ reaction mixtures with beneficial flow characteristics allowing sufficient agitation of all parts of these reaction mixtures and thus achieving adequate mixing of reaction partners and/or dissipation of heat. The beneficial flow characteristics are achieved by using suitable activation for coupling the terminal pyridine-carboxylic acid.
