By matching numbers across the arrow, you can see<br />

where atoms move during the course of the<br />

reaction. The other reaction (not observed<br />

experimentally) in which the ester oxygen comes<br />

from the acid, would be mapped like this:<br />

1<br />

3<br />

O<br />

2<br />

OH 4<br />

5<br />

E-Notebook uses atom-to-atom map information<br />

to determine the reacting centers for reactions. If<br />

only some atoms are mapped, E-Notebook uses<br />

that information and does not worry about the<br />

specific fates of other atoms. Foe example, if you<br />

do not know (or do not care) about the mapping of<br />

certain atoms, you can leave them unspecified in<br />

the-atom-to-atom map.<br />

Searching for Reactants<br />

If you know what starting materials you are<br />

interested in but do not know their products, you<br />

might perform a reactants query. A reactants query<br />

is very similar to a reaction search, except that there<br />

is nothing to the right of the arrow. For example,<br />

consider the query:<br />

O<br />

Rxn<br />

OH 6<br />

1<br />

3<br />

O<br />

2<br />

O Rxn<br />

4<br />

5<br />

H 2 O 6<br />

Searching for Products<br />

If you know the desired end product but not how<br />

to get there, you can do a products query. A<br />

products query is similar to a reaction search,<br />

except that there is nothing to the left of the arrow.<br />

For example, consider the query:<br />

If you are doing a substructure search, this finds any<br />

reactions in which bicyclo[2.2.1]heptane or a<br />

compound containing its substructure is produced.<br />

Searching with the<br />

Search Location Field<br />

The search location field makes it possible for you<br />

to select the specific branch of the collection tree<br />

over which your search is conducted.<br />

To use the search location field:<br />

1. While in Search mode with a search form<br />

displayed, click the Search In... checkbox to<br />

activate the field.<br />

O<br />

O<br />

If you are doing a substructure search, this finds any<br />

reactions in which maleic anhydride or a compound<br />

containing a maleic anhydride substructure is<br />

consumed or transformed.<br />
