DERIVATIVES OF PROPEN ACID POSSESSING ANTIFUNGAL ACTIVITY

1. Technical result Reception of new derivatives of propen acid, having high antifungal action. 2. Essence Derivative of propen acid of the general formula: And their stereoisomers Where R1-C1-C4-alkyl, C1-C4-alkoxy, СООR3 where R3-C1-C4-alkyl, РО/OR3/2СОR4, R4-C1-C4-alkyl or phenyl or R1 benzil, phenyl, piridil or its N-оксид, pyrimidinil, pyrazinil, pyridazinil, quinolyl, pyrrolil, tiazolil, furanil, triazinil, benzi tazolil, benzo xazolil, izo xazolil, thienyl, quinoxalynil, phenyletenil, ) oxazolid, C1-C4-alkylthio, thus, phenyl and each heterocyclic residuum can be substituted one or two phenyl substituted cyano, phenoxy, pirimidiniloxy, benziloxy, CO2R3, CONH2, SR3, R2 - hydrogen, halogen, C1-C4-alkyl, CF3, C3-C6-cycloalkyl, pirimidinil, amino, di (C1-C4) alkyl amino, imidazole, pyrrodil, pyridil, C1-C4-alkoxy, S (O) nR, n=0,1 CO2R3 cyano and where R3 = C1-C4-alkyl, or R1-R2 together create cyclic system is substituted C1-C4-alkyl, khalo (C1-C4)-alkyl, C1-C4-alkoxy, halo (C1-C4)-alkoxy, C2-C4-alkeniloxy, amino, nitro, cyano, SO2R3: Or On condition that when R1-pirimidinil, R2 cannot be SC2H5, or OC6H5. 3. Field of Application Organic chemistry, agriculture.
