| Introduction |
This section describes how to locate organic synthetic methods based on chemical functional groups using Explore by Chemical Substance or Reaction.
|
| When to use |
Use functional group searching when you want to find methods used to carry out a broadly defined transformation.
|
| Database content |
Functional group searching accesses the CASREACT database. Records in CASREACT focus on synthetically useful procedures. For example:
- New, more convenient, or improved synthetic methods
- Procedures for improving yields
- Applications of new reagents
|
| Reaction precision tools |
Tools are available to control the precision of functional group search results:
|
When you want to |

| How to |
Follow these steps to locate a functional group transformation. |
|
Step |
Do this |
| 1 |
From the New Task dialog box, click Explore  . |
| 2 |
From the Explore dialog box, click Reaction Structure  . |
| 3 |
The structure drawing window appears. Draw the reaction transformation of interest. Click Get Reactions. Apply the following tools to control answer precision:
|
| 4 |
The Get Reactions dialog box appears. Select the substructures option. Click OK.
|
| 5 |
The reaction viewer containing all the reaction matches appears.
| When you want to see |
Do this |
|
Information about a specific reaction participant, such as
- Reactions in which the specific substance participates (SciFinder subscription users only)
- References about the substance
- Substance detail, e.g., CAS RN, names, or properties
- Commercial sources
- Regulatory information
|
- Position the cursor over any structure or CAS RN in a reaction.
- Click.
|
| The reference citing the reaction |
Reference: hyperlink |
| A smaller set of more precisely defined reaction matches |
Click Analyze/Refine  .
The Analyze or Refine dialog box appears. Click Refine  .
The Refine by Reaction dialog box appears. Click Chemical Structure, Product Yield, Number of Steps, or Reaction Classification.
