ABSTRACT:
New fungicidal spiroheterocyclic compounds are described, having the general formula I, ##STR1## or an acid-addition salt thereof, in which R.sup.1 or each R.sup.1 independently represents an optionally substituted alkyl, cycloalkyl, cycloalkylalkyl, alkoxy, cycloalkoxy, alkoxyalkyl, aralkyl, aryl or aryloxy group, or R.sup.1 or each R.sup.1, together with the ring to which they are attached, represents an optionally substituted polycyclic hydrocarbyl group,
R.sup.2 represents a hydrogen atom or a C.sub.1-4 alkyl group,
R.sup.3 represents a hydrogen atom, a hydroxy group or an optionally substituted alkoxy or acyloxy group,
R.sup.4 and R.sup.5 each independently represent a hydrogen atom, an optionally substituted alkyl, alkenyl, alkynyl, cycloalkylalkyl, cycloalkyl, bicycloalkyl, tricycloalkyl, alkoxyalkyl, aryl, aralkyl, haloaralkyl, a 4- to 6- membered heterocyclyl, tetrahydrofurfuryl or dioxolanyl group, or R.sup.4 and R.sup.5 together represent an optionally substituted, saturated or unsaturated carbon chain which may optionally contain one or more oxygen atoms and which may optionally be aryl- or cycloalkyl-fused,
m represents zero or an integer from 1 to 6, and
p represents zero or an integer from 1 to 3.
The invention further relates to the preparation of the above spiroheterocyclic compounds, intermediates prepared during the synthesis of these compounds, compositions containing the compounds and their use as fungicides in the control of phytopathogenic fungi.
