FUNGICIDIC SPIROHETEROCYCLIC DERIVATIVES AND THEIR ACID-ADDITIVE SALTS, METHOD OF SYNTHESIS, FUNGICIDIC COMPOSITION AND METHOD OF FUNGI CONTROL

摘要

FIELD: organic chemistry. SUBSTANCE: product: new spiroheterocyclic compounds of the general formula (I): or their acid-additive salts where: R¹ or each R¹ means independently optional substituted alkyl, cycloalkyl, cycloalkylalkyl, alkoxy, cycloalkoxy, alkoxyalkyl, aralkyl, aryl or aryloxy-group, or R¹ and each R¹ together with ring to which they were bound mean optional the substituted polycyclic hydrocarbon group; R² means hydrogen atom or C_1-4-alkyl group; R₃ means hydrogen atom, hydroxy-group optional substituted with alkoxy- or acylhydroxy-group; R₄ and R₅ each independently means hydrogen atom, optional substituted alkyl, alkenyl, alkynyl, cycloalkylalkyl, cycloalkyl, bicycloalkyl, tricycloalkyl, alkoxyalkyl, aryl, aralkyl, haloidalkyl, 4-6-membered heterocyclic, tetrahydrofurfuryl or dioxolanyl group, or R₄ and R₅ together mean optional substituted suturated or unsaturated carbon chain that can contain optional one or more oxygen atoms and can be optional aryl or cycloalkyl fused ring; m = 0-6 and p = 0-3. Invention relates to synthesis of above indicated spiroheterocyclic compounds, intermediate compounds synthesized, compositions containing these compounds and their use as fungicides for phytopatogenic fungi control. EFFECT: improved method of synthesis.
