Fungicidal compounds of formula (I): where X is O or S; RING is phenyl or thienyl; Het is a 5- or 6-membered heterocyclic ring containing one to three heteroatoms, each independently selected from oxygen, nitrogen and sulphur, the ring being substituted by one to four groups R4 ; R1 is hydrogen, optionally substituted (C1-4)alkyl, formyl, optionally substituted (C1-4)alkylC(=O), optionally substituted (C1-4)alkylC(=O)O, optionally substituted (C1-4)alkoxy(C1-4)alkyl, optionally substituted allyl, optionally substituted propargyl or optionally substituted allenyl; each R2 is, independently, halogen, optionally substituted (C1-4)alkyl, optionally substituted (C1-4)alkoxy or optionally substituted (C1-4)alkoxy(C1-4)alkyl; R3 is (CRaRb)m_Cy-(CRCRd )n-Y; each R4 is, independently, selected from halogen, C1-3 alkyl, C1-3 haloalkyl, C1-3 alkoxy(C1-3)alkyl and cyano; Ra, Rb, Rc and Rd are each, independently, hydrogen or optionally substituted (C1-4)alkyl; Cy is an optionally substituted carbocyclic or heterocyclic 3-7 membered ring which may be saturated, unsaturated or aromatic and which optionally contains a silicon atom as a ring member; (CRaRb)m and (CRcRd)n may be bound either to the same carbon or silicon atom of Cy or to different atoms separated by 1, 2 or 3 ring members; Y is Si(OpZ1)(Oq Z2)(OsZ) and provided that Cy contains a silicon atom as a ring member then Y may also be hydrogen; Z is C1-4 alkyl or C2-4 alkenyl (each of which is optionally interrupted by one heteroatom selected from O, S and N and is optionally substituted by one to three independently selected halogen atoms); Z1 and Z2 are, independently, methyl or ethyl; in and n are each, independently, 0, 1, 2 or 3; p, q and s are each, independently, 0 or 1; and r is 0, 1 or 2; or an N-oxide thereof; novel intermediates used in the preparation of these compounds, agrochemical compositions which comprise at least one of the novel compounds as active ingredient and the use of the active ingredients or compositions in agriculture or horticulture for controlling or preventing infestation of plants by phytopathogenic microorganisms, preferably fungi.
式(I)的杀真菌化合物:其中X为O或S;RING为苯基或噻吩基;Het为一个含有1-3个杂原子的5-6元杂环,每个杂原子独立地选择自氧、氮和硫,该环被1-4个R4基取代;R1为氢、可选地取代的(C1-4)烷基、甲酰基、可选地取代的(C1-4)烷基C(=O)、可选地取代的(C1-4)烷基C(=O)O、可选地取代的(C1-4)烷氧基(C1-4)烷基、可选地取代的烯丙基、可选地取代的丙炔基或可选地取代的芳基;每个R2独立地为卤素、可选地取代的(C1-4)烷基、可选地取代的(C1-4)烷氧基或可选地取代的(C1-4)烷氧基(C1-4)烷基;R3为(CRaRb)m_Cy-(CRCRd)n-Y;每个R4独立地选择自卤素、C1-3烷基、C1-3卤基烷基、C1-3烷氧基(C1-3)烷基和氰基;Ra、Rb、Rc和Rd各自独立地为氢或可选地取代的(C1-4)烷基;Cy是一个可选地取代的碳环或杂环3-7元环,可能是饱和的、不饱和的或芳香的,并且可能作为环成员包含硅原子;(CRaRb)m和(CRcRd)n可以结合到Cy的同一碳或硅原子上,也可以结合到相隔1、2或3个环成员的不同原子上;Y为Si(OpZ1)(OqZ2)(OsZ),如果Cy含有硅原子作为环成员,则Y也可以是氢;Z为C1-4烷基或C2-4烯基(每个烷基或烯基可以被来自O、S和N的一个杂原子中断,并且可以被1-3个独立选择的卤素原子取代);Z1和Z2独立地为甲基或乙基;in和n各自独立地为0、1、2或3;p、q和s各自独立地为0或1;r为0、1或2;或其N-氧化物;用于制备这些化合物的新型中间体、包含至少一种新型化合物作为活性成分的农药组合物以及将活性成分或组合物用于农业或园艺,以控制或预防植物受到植物病原微生物(优选为真菌)的侵害。
