Darstellung neuer substituierter 1,2,4-Triazin-6-carbonsäuren und 1,2,4-Triazin-6-yl-alkancarbonsäuren

Synthesis of New Substituted as-Triazine-6-carboxylic Acids and as-Triazine-6-yl-alkanoic Acids New substituted 3-amino-, 5-amino- and 3,5-diamino-as-triazine-6-carboxylic acids 4a , b , 5a , b and 6 were obtained by the hydrolysis 6-azalumazine derivatives 3a – e . Corresponding acids of the structure 10a – d , 11a , b and 12 were synthesized from 5-chlor-3-methylthio-astriazine-6-carboxylic-ester 8 . The synthesis of new 3-alkylthioderivatives of as-triazine-6-yl-acetic acid 16a – c and -propionic acid 18 and its hydrolysis to 3,5-dioxotetrahydro-as-triazine-6-yl-propionic acid 19 is reported.
