Claim 1, which is illustrative of the subject matter on appeal, reads as follows:
1. A compound having the formula:
wherein X represents a single or a double bond; R1 is H or OH; provided that when
X is a single bond, R1 is H or OH, and when X is a double bond, R1 is absent;
R2 is H, C1-C8 alkyl, C2-C8 alkenyl, C2-C8 alkynyl, alkoxy-alkyl or alkylthioalkyl
containing from 1 to 6 carbon atoms in each alkyl or alkoxy group, wherein any of
said alkyl, alkoxy alkenyl or alkynyl groups may be substituted by one or more halo
atoms or a C3-C8 cycloalkyl or C5-C8 cycloalkenyl group, either of which may be
substituted by methylene or one or more C1-C4 alkyl groups or halo atoms; or a 3 to
6 membered oxygen or sulphur containing heterocyclic ring which may be saturated,
or fully or partially unsaturated and which may be substituted by one or more C1-C4
alkyl groups or halo atoms; or a group of the formula SR5 wherein R5 is C1-C8 alkyl,
C2-C8 alkenyl, C2-C8 alkyny1, C3-C8 cycloalkyl, C5-C8 cycloalkenyl, phenyl or
substituted phenyl wherein the substituent is C1-C4 alkyl, C1-C4 alkoxy or halo, or a
3 to 6 membered oxygen or sulphur containing heterocyclic ring which may be
saturated, or fully or partially unsaturated and which may be substituted by one or
more C1-C4 alkyl groups or halo atoms;
