Carbocyclic Ring Bonded Directly To The Nitrogen Patents (Class 544/165)
  • Patent number: 4064270
    Abstract: A new class of N'-(aminoacylaminophenyl) acetamidines: ##STR1## in which R.sup.1 and R.sup.2 are the same or different and represent hydrogen, alkyl, aryl or the substituted derivatives thereof or, together with the nitrogen atom to which they are attached, an heterocyclic ring; and R.sup.3 is hydrogen, alkyl, aryl, aralkyl, or a heterocyclic moiety including the substituted derivatives thereof. The products have utility as anthelmintics.The products are obtained by treating a suitable amino-acid or a carbonyl-activated amino-acid, with the appropriate N'-(4-aminophenyl)-N,N-dimethylacetamidine. In addition, the products are obtained by treating a suitable N'-(haloacylaminophenylacetamidine with an appropriate amine.

  • Patent number: 4059623
    Abstract: Substituted 2-(carbamoyl)oxyimino-3-iminobutyramides and 2-(carbamoyl)oxyimino-3-iminobutyrates of the formula ##STR1## where Q is --OR.sub.4 or --NR.sub.5 R.sub.6, and A, R, R.sub.2, R.sub.3, R.sub.4, R.sub.5, and R.sub.6 are as hereinafter defined are useful as aphicides. The compounds are made by reacting an amine with a substituted 2-hydroxyiminoacetoacetamide (or 2-hydroxyiminopropionylacetamide) or an alkyl 2-hydroxyiminoacetoacetate (or 2-hydroxyiminopropionylacetate), then carbamylating the resulting substituted 2-hydroxyimino-3-iminobutyramide (or 2-hydroxyimino-3-iminovaleramide) or 2-hydroxyimino-3-iminobutyrate (or 2-hydroxyimino)-3-iminovalerate).
