There is provided di-substituted iminoheterocyclic compounds of the following formula (I):
1
in which,
A is optionally substituted alkyl group, optionally substituted aryl group or optionally substituted heterocyclic group;
X is oxygen atom, sulfur atom, carbon atom or nitrogen atom;
the group —X—Y— represents optionally substituted alkylene or cyclic alkenylene bond; and
B
1
and B
2
are, hydrogen atom, optionally substituted alkyl group, optionally substituted aryl group or optionally substituted heterocyclic group, independent from each other,
