Functional Group Searching
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

Use this tool

Draw a reaction arrow and automatically define the participant roles:

  • reactant/reagent on left
  • product on right

Example

Using cyclic ketones as the starting material, locate preparations of compounds with this structure:

How to Follow these steps to locate a functional group transformation.

Step

Do this

1 From the New Task dialog box, click Explore explore.
2 From the Explore dialog box, click Reaction Structure explorereacts.
3

The structure drawing window appears. Draw the reaction transformation of interest. Click Get Reactions.

Apply the following tools to control answer precision:
  • Functional Group tool functionalgrouptool to define the starting material
  • Reaction Arrow tool to define the reaction participants
  • Lock Out Rings tool to control ring formation
  • Lock tool to control substitution

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
  1. Position the cursor over any structure or CAS RN in a reaction.
  2. Click.

Click Analyze/Refine Analyze Refine.

The Analyze or Refine dialog box appears. Click Refine refine.

The Refine by Reaction dialog box appears. Click Chemical Structure, Product Yield, Number of Steps, or Reaction Classification.
