  • Patent number: 6632950
    Abstract: Novel processes and intermediates are provided for the synthesis of derivatives of 4-amino-3-hydroxypyrrole-2-carboxylic acids that are useful as monomers for polyamides capable of binding dsDNA. According to one preferred reaction scheme, an alkyl alkoxymethylene nitroacetate (Formula VIII) is prepared by reaction of a trialkyl orthoformate or orthoacetate with a nitroacetate ester in the presence of a carboxylic anhydride. The compound of Formula VIII is condensed with an N-substituted glycine to yield an N-substituted (2-nitro-2-alkoxycarbonyl)vinyl glycinate ester (Formula VII). Ring closure in the presence of an alkali metal alkoxide yields a 4-nitro-3-hydroxypyrrole-2-carboxylic ester (Formula V). After blocking of the 3-hydroxy group to produce a further intermediate (Formula IV), the 4-nitro group is reduced to a 4-amino group (Formula III), and the 4-amino group is then blocked by reaction with a dicarbonate diester to produce the fully blocked intermediate (Formula II).
