Abstract

NOVI SUPSTITUISANI 3-CIJANO-2-PIRIDONI I POSTUPAK ZA NJIHOVO DOBIJANJE, pronalazak se odnosi na nova jedinjenja, supstituisane 3-cijano-2-piridone opšte formule posebno na 4,6-disupstituisane-3-cijano-2-piridone, opšte formule gde supstituenti R1,R2,R3 i R4 mogu biti vodonik, alkil, aril ili heterociklična grupa ili supstituisane alkil, aril ili heterociklične grupe. Pronalazak se takodje odnosi na nove postupke za sintezu supstituisanih 3-cijano-2-piridona, u kojima se umesto uobičajenih katalizatora navedenih u literaturi, koriste i novi menjači jona i enzimi.The invention relates to new compounds, substituted 3-cyano-2-pyridones of the general formula, in particular to 4,6-disubstituted-3-cyano-2-pyridones, of the general formula wherein the substituents R1, R2, R3 and R4 may be hydrogen, alkyl, aryl or a heterocyclic group or substituted alkyl, aryl or heterocyclic groups. The invention also relates to new processes for the synthesis of substituted 3-cyano-2-pyridones, in which new ion exchangers and enzymes are used instead of the usual catalysts listed in the literature.
