you can manually readjust the reaction mapping.
The figure below shows the initial mapping being amended by using the Reaction Atom-Atom Map tool.
Figure 11.19: Automatic mapping to be amended
When you manually map reactions with the Reaction Atom-Atom Map tool, you can suppress automatic re-mapping
of atoms other than your target atom.
To suppress automatic remapping:
1. Go to File>Preferences.
2. On the General tab, de-select Automatic Reaction Mapping.
3. Click OK.
To use the Reaction Atom-Atom Map tool to supplement the automatic mapping:
1. Click the Reaction Atom-Atom Map tool on the Query toolbar.
2. Point to the atom in the reactant whose mapping you want to establish. For example, in the following drawing you
would point to the acyclic carbon adjacent to the ether oxygen.
3. Drag from the reactant atom to the corresponding product atom.
The remaining atoms are mapped based on the manual mapping.
