Intermediates for heterocyclic compounds having fungicidal or plant growth regulatory activity are compounds having the general formula (II):
and stereoisomers thereof, wherein:
Q is phenyl or aralkyl having one to four carbon atoms in the alkyl moiety, optionally substituted with one or more substituents selected from halogen, haloalkyl, C1-4alkyl, C1-4 alkoxy, phenyl and phenoxy;
or Q is C1-6alkyl;
R², R³, R⁴, R⁵ and R⁶, which may be the same or different, is each H, C1-6alkyl, C3-6cycloalkyl, or is phenyl or aralkyl having one to four carbon atoms in the alkyl moiety, optionally substituted with one or more substituents selected from halogen, haloalkyl, C1-4alkyl, C1-4alkoxy, phenyl and phenoxy; and
R⁷ and R⁸, which may be the same or different, are alkyl or alkenyl groups or together form a ring.
Other compounds and their use in preparing compounds of general formula (II) are described.
