  • Patent number: 6541630
    Abstract: The invention provides the use in combating fungi of compounds of general formula I wherein R1 is hydrogen, hydroxy, acyl, acyloxy, optionally substituted amino, Ra, Ra3Si, RaS or RaO, where Ra is optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted cycloalkyl, optionally substituted cycloalkenyl, optionally substituted aryl or optionally substituted heterocyclyl; Z is oxygen or sulfur; M is a thiophene ring; and R3 and R4, which may be the same or different, have the same meaning as Ra or can be optionally substituted amino, hydrogen, halogen, cyano, nitro or a group ORc or S(O)mRc, where Rc has the same meaning as Ra or is hydrogen or acyl and m is 0, 1 or 2; or R3 and R4 together with the atoms to which they are attached form an optionally substituted carbocyclic or heterocyclic ring; together with tautomers of compounds where R1 is hydrogen.
